# Tendos alternatives: AI for manufacturers, dealers or contractors? (2026)

> Tendos alternatives compared: Tendos automates sales for manufacturers. What building-material dealers and construction companies need instead, with Streckenheld, Vestigas and Comstruct.

Tendos builds AI agents for the sales teams of manufacturers in the construction industry: finding tenders, preparing inquiries, matching bills of quantities to their own products and taking orders into the ERP. People looking for alternatives often sit somewhere else in the supply chain, as a building-material dealer between manufacturer and site, or as a construction company that sends out the bills of quantities. This comparison places Tendos along that chain and sets out three alternatives side by side.

## Tendos at a glance

Tendos describes itself as an "AI platform for manufacturers in the construction industry". Its homepage speaks directly to inside sales: Tendos finds tenders and processes inquiries, quotes and orders, automated where possible and steered by the team where it matters.

**The modules according to its website:**

- **Tenders:** Tendos searches tenders and project data, filters them by the manufacturer's portfolio and brings matching projects into its system.
- **Inbox:** emails and attachments are read and recognised as an inquiry, order or follow-up question, assigned to the right contact and given a suggested next step.
- **Quotes:** "LV in, quote out." Tendos reads bills of quantities as PDF, GAEB, Excel, email or free text, matches each line to an item from the manufacturer's catalog and distinguishes own, neutral and third-party products. Matching accessories and sets are added, and configuration parameters are prepared for configurators, CPQ systems and SAP KMAT. Uncertain lines are flagged for review; the team checks and releases. Output is PDF, GAEB or Excel.
- **Order capture:** orders from email, PDF or EDI are read, item numbers matched to the catalog and inconsistencies flagged, for example when an item number and its description don't match. If a quote exists, the order is linked to it. After review, the order goes to the ERP in one click.
- **Integrations:** quotes, orders and master data sync in both directions with CRM and ERP; Salesforce, SAP, Microsoft Dynamics and Outlook are named. According to its FAQ, Tendos does not replace the ERP or CRM.
- **Data & insights:** inquiry volume, hit rates and competitor activity, drawn from the team's own deals.

**Profile:**

- **Built for:** manufacturers in the construction industry, especially sales, inside sales and sales management
- **Rollout:** "in a few weeks" according to its website; during onboarding the agents learn products, pricing logic and catalog structure, then learn from every correction
- **Data protection:** ISO 27001-certified server infrastructure in Europe, separated customer instances, SSO, no model training on customer data
- **Website languages:** German, English, French, Spanish, Italian, Polish

**Strengths:** Tendos is built around one task: turning someone else's bill of quantities into a quote with your own products, fast. Matching lines to large technical catalogs with variants, accessories and configurable products is its core. On top come tender discovery, a pre-sorted inbox and analytics for sales management.

## Why companies look for alternatives to Tendos

Tendos works on the manufacturer's sales side. Many people looking for alternatives have a different role in the supply chain and therefore different tasks:

- **Building-material dealers** don't only sell. They plan deliveries, collect delivery notes from manufacturers, pass documents on to customers and re-invoice drop shipments. When the manufacturer delivers straight to site, its invoice has to be reissued at that customer's prices. Re-invoicing, delivery-note management and route planning are not described on the Tendos website.
- **Construction companies** sit on the other side of the quote: they send out the bill of quantities, compare several bids and later check delivery notes and invoices. RFQs to several suppliers, a [price matrix](https://www.streckenheld.com/knowledge/bid-comparison.md), order approvals, invoice checking and payment approval are not part of Tendos, which its website says is built specifically for manufacturers.
- **Manufacturers with drop shipments or logistics:** if you also want to digitise delivery notes, call-offs and the document chain with dealers and sites, you need another tool; on the Tendos website the described workflow ends when the order is handed to the ERP.

## The alternatives

### 1. Streckenheld: AI agents for building-material dealers and construction companies

Streckenheld is an AI platform for the two roles that sit opposite Tendos: building-material dealers and construction companies.

**For building-material dealers**, three agents each take one step of a delivery:

- **Route planning and dispatch:** the agent bundles open deliveries into routes, checks time windows, weight and pallets, and dispatches in one click to your own fleet, partner carriers or the Streckenheld network of more than 1,000 logistics partners. Construction companies get live tracking and digitally signed delivery notes. More on the [route planning and dispatch](https://www.streckenheld.com/route-planning-dispatch.md) page.
- **Document management:** delivery notes, order confirmations and invoices that today travel by email, fax and post between manufacturers, dealer and customers land in one place. The agent collects delivery notes from manufacturers automatically and sends delivery notes, order confirmations and invoices to your customers.
- **Re-invoicing (AI order management):** the agent reads the manufacturer's invoice for a drop shipment, recognises the manufacturer, customer and site, and creates the outgoing invoice at that customer's prices. The catalog is built from pairs of past invoices, including the mapping from the manufacturer's item number to your own and customer- or site-specific prices and discounts. Exceptions go to a person, approved invoices go to the ERP. By our own figures, the agent automates around 80% of the manual invoicing work. More on the [re-invoicing](https://www.streckenheld.com/re-invoicing.md) page.

**For construction companies**, Streckenheld covers purchasing from the RFQ to payment: a bill of quantities is analysed with AI and sent as an RFQ to several suppliers; the bids land in a line-by-line price matrix. Then come ordering with multi-step approval, a [document inbox](https://www.streckenheld.com/guides/document-inbox.md) for delivery notes, order confirmations and invoices, the 4-way match and payment approval with a SEPA file. GAEB is imported (X80 to X86) and exported as X83/X84.

- **Strengths:** dedicated agents for the building-material trade, rules as AI instructions, typical two-week onboarding, connections to construction ERPs such as BRZ, Nevaris, RIB and PDS, EU hosting without training on customer data.
- **Keep in mind:** Streckenheld does not create sales quotes from bills of quantities for manufacturers. Prices are not public.
- **Best for:** building-material dealers with drop shipments and their own logistics, and construction companies that want purchasing and document checks in one platform.

### 2. Vestigas: a digital supply chain with delivery notes via EDI

Vestigas describes itself as an "AI supply chain for construction & industry" and offers digital orders, delivery notes and AI-supported invoice checking. According to its website, delivery notes arrive via EDI straight from the ERP of more than 1,000 connected suppliers; for the rest there is an AI scan and a free supplier portal. On top come an offline site app with a GoBD-compliant signature, framework contracts and call-offs, a 3-way match, concrete testing and CO₂ reporting.

- **Strengths:** large EDI network, free for suppliers, explicitly aimed at building-material and building-services dealers, mixing plants and manufacturers as well.
- **Not described on its website:** quotes from bills of quantities, re-invoicing of drop shipments, route planning.
- **Best for:** companies that want to exchange delivery notes and call-offs digitally between plant, dealer and site. More in the [Vestigas alternatives](https://www.streckenheld.com/alternatives/vestigas.md) comparison.

### 3. Comstruct: AI agents for purchasing at large construction companies

Comstruct calls itself "AI agents for construction" and automates purchasing "from the bill of quantities to the checked invoice". In a sense it is the counterpart to Tendos: the BoQ becomes a structured enquiry, lines are grouped by material category and sent to suitable suppliers, and bids are compared line by line. Then come call-offs with an approval chain, delivery notes from paper, PDF, EDI or photo, and invoice checking against the BoQ, framework contract and delivery note.

- **Strengths:** chain from the BoQ through the enquiry to the invoice, experience with large general contractors and infrastructure projects, ISO/IEC 27001.
- **Not described on its website:** features for manufacturers or the building-material trade, order-confirmation check, payment approval.
- **Best for:** large general contractors and infrastructure builders in Switzerland and Germany. More in the [Comstruct alternatives](https://www.streckenheld.com/alternatives/comstruct.md) comparison.

"Not described" means not described on the provider's website (as of October 2026). That does not rule out that a feature is available in individual cases.

## When Tendos is still the right choice

- **You are a manufacturer** of building materials or building technology, and your inside sales team answers many tenders and bills of quantities.
- **Your catalog is large and technical**, with variants, nominal sizes, performance levels, accessories and configurable products that need matching line by line.
- **Third-party products in the BoQ** should be recognised and replaced with your own items.
- **You want to find projects early**: tender discovery and analysis of hit rates and competitors support sales management.
- **Salesforce, SAP or Dynamics** are set, and quotes and orders should end up there.

## Where Streckenheld is different

**A different role in the supply chain.** Tendos helps the manufacturer sell faster. Streckenheld helps the building-material dealer plan deliveries, handle their documents and invoice them, and helps the construction company buy and check. If you are a manufacturer and want to create sales quotes from bills of quantities, Tendos is the right place; if you are a dealer or a construction company, Streckenheld has the agents for you.

**Built for the building-material trade.** The dealer sits between manufacturer and site and handles both sides of the paperwork: delivery notes and invoices from manufacturers on one side, order confirmations, delivery notes and invoices for customers on the other. Streckenheld works right there:

- The manufacturer's invoice for a drop shipment becomes the outgoing invoice to the customer, priced by the most specific rule: a catalog price for this site, this customer or all customers, then supplier, customer and global discounts. Every line shows where its price comes from.
- Instructions to the AI handle special cases, for all invoices, per manufacturer or for a single invoice, for example "re-invoice Euro pallets as deposit at purchase price without discount".
- Delivery notes are requested from manufacturers automatically and passed on to customers together with order confirmations and invoices.
- Routes are built from the data dispatch already has and assigned in one click to your own fleet, partners or the Streckenheld network.

**And for the construction companies that are your customers.** On the same platform, construction companies send RFQs, compare bids, order with approvals and check delivery notes and invoices in a 4-way match. Suppliers answer RFQs without an account in the web form or by PDF, manufacturers and dealers included.

**Bottom line:** Tendos specialises in sales for manufacturers and is strong at matching bills of quantities to large technical catalogs. For building-material dealers who want to automate dispatch, documents and re-invoicing, and for construction companies that want to bring their purchasing together, Streckenheld is the alternative.

## Frequently asked questions

### Who is Tendos built for?

According to its website, Tendos is an AI platform built specifically for manufacturers in the construction industry. Its agents support manufacturers' sales and inside-sales teams: finding tenders, preparing inquiries and orders from the inbox, matching bills of quantities to their own products and handing orders over to the ERP (as of October 2026).

### Is Tendos suitable for building-material dealers?

The website is aimed at manufacturers; dealers appear there only as business partners in examples. Typical dealer processes such as re-invoicing drop shipments, collecting manufacturers' delivery notes or route planning are not described on its website (as of October 2026). Streckenheld has dedicated AI agents for these tasks.

### What is the best alternative to Tendos?

It depends on where you sit in the supply chain. For a manufacturer's sales team, Tendos is specialised. Building-material dealers find agents for route planning and dispatch, document management and re-invoicing in Streckenheld. Construction companies that send RFQs, compare bids and check invoices on the buying side compare Streckenheld, Comstruct and Vestigas.

### Can Tendos and Streckenheld be used together?

Yes, they sit on different sides of the same supply chain. A construction company or dealer sends an RFQ through Streckenheld; the manufacturer can enter its prices in the web form without an account or upload a PDF, for example one prepared with Tendos. The offer then lands in the buyer's price matrix.

### Where is the data hosted?

According to its website, Tendos uses ISO 27001-certified server infrastructure in Europe, separated customer instances and does not train models on customer data. Streckenheld hosts in the EU and does not train models on customer data either.
