Getting the right signed acceptance form to billing

Short answer

Acceptance certificate automation links the signed document to the project and the scope of work, then passes it to the person who prepares billing. A draft saved later in the same folder does not reach the invoice. At Syntalith the automation costs from €3,000 net, and with 150 certificates a month at 15 minutes of searching each it pays back in 2.9 months.

Figures checked: 22 October 2026

Acceptance certificates: one floor accepted, the rest of the installation in progress

A company is fitting an installation on two floors. The client signed a partial acceptance certificate for the first floor, and work on the second floor continues. After the signed document arrived, the site manager saved an unsigned draft certificate for the whole installation in the same folder. So the newest file is a draft for all the work. Choosing by save date would send the wrong document to billing and an invoice for work the client has not yet accepted.

The automation links the returned document to the project and shows its actual scope. The billing employee opens the certificate and checks the payment terms agreed for the project. The signature helps establish which document came back from the client, and it does not answer what to invoice and when. The site manager still clarifies an unclear scope and comments, and stops forwarding every file by hand.

The certificate's path to billing

  2. 02Linkthe project, stage and scope of acceptance read from the document
  3. 03Distinctionthe signed version kept apart from drafts

  5. 05Correctiona new version appears next to the previous one with the reason for the change

First use the signing workflow you already have

If certificates come back to one mailbox with one template and a project number, an email rule and a tidy folder are enough. With electronic signatures, the platform handles part of the handover. Docusign describes Agreement Actions, which, once a workflow is complete, save the documents in a connected store or start the next workflow. The status completed means all recipients have finished their actions (status definition). The scope of the accepted work still has to be read from the certificate.

What to choose for which workflow
  • One mailbox, one template, the project number in the name

    an email rule and a folder

    no AI

  • Electronic signature on one platform

    configuration

  • Different layouts, names and photos of documents from clients

What acceptance certificate automation costs and when it pays back

Scenario: 150 acceptance certificates a month
Today
150 certificates × 15 min = 37.5 h (€1,309)
With the system, a person checks the output in 20% of the time

Payback of €3,000

2.9 months

The volume, the time and the checking share are the scenario's assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat. Model: 3,000 input tokens and 400 output tokens per call at Anthropic's rates, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026.

An illegible project number or a missing page with the scope of work goes to the person who can clarify the case. When a correction arrives, the employee sees it next to the earlier certificate. If it is unclear whether the new document replaces the previous one, the site manager records the decision with the file, and the next person sees which version was chosen and why.

Where to start

The first scope covers one type of certificate and one way of receiving it. On known documents, the site manager and the billing employee check that they get the right file with the correct scope and that a draft goes no further. The site manager's wider work when closing a project is covered in the article on closing a services project. We build the workflow as part of our AI automations, and for the free process review a description of the last certificate someone had to search for is enough: where it came back, who needed it and how you recognised the right version.

€2,327

a month for matching 1,000 documents to cases by hand

Payback: 1.5 mo.

4 minutes per document matched to a case and checking in 15% of the old time are our assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. Model cost: reading a document in our case-file system (about €0.0002) plus matching it to the case and a note on what is missing (Claude Sonnet 5.5, about 2,000 + 300 tokens), at the ECB rate of 1.1205 USD per euro on 22 October 2026.

foap.comcustomer service

foap.com customer service: 95% of replies are sent automatically.

Users from several countries write to foap.com, in several languages. The system reads the entire conversation and the terms of that person, and then sends a response in that person's language. Questions about money and exceptions go to the team with a ready draft, so they have to check and send them.

Data checked on October 25, 2026.

„Is my data safe?”

Yes. You choose where they go: from your company account to the model on your server.

  1. 00Employee's private account

    Customer and company data ends up in an account that the company cannot see or control. There is no data processing agreement, so it is a violation of the GDPR. When an employee leaves, the chat history goes with them.

  2. 01ChatGPT or Claude corporate account

    The provider does not use your data to train models. A copy of the queries remains in his logs for up to 30 days.

  3. 02API with zero retention (ZDR)

    The provider processes the request and does not save anything. It requires his consent, we prepare the application together.

  4. 03Processing in the EU

    Queries are counted and stored in Europe: OpenAI in the EU region, Claude via clouds with the EU region.

  5. 04Model at your place

    The open model runs on your server or in your cloud in the EU. The data does not go outside the company.

What we do with every implementation

  • Confidentiality agreement and data processing agreement before we receive any data.
  • You choose the cases for the prototype and we anonymize them upon request.
  • The data stays in the EU and we delete it after the test.
  • Corporate accounts with an administrator on your side.

When data cannot leave the company

The open model runs on your server or in your cloud in the EU. To choose from:

Do you have a lot of your own data? We will fine-tune the small model.

  1. 1 Your examples
  2. 2 tuning
  3. 3 test on new cases
  4. 4 model at your place

When you have thousands of similar emails, documents or reports, we teach a small open model based on your examples. It works for you, responds quickly and costs less to maintain than a large model. We measure quality on issues that the model has not seen while learning.

Przemysław and Piotr did it in large programming and consulting companies. Artem did it before and does it today at Syntalith. It's about models on your own infrastructure, tuning and quality measurement.

AI automations

This process can go on its own. You will check this on your cases before you pay.

The system takes over repetitive work from emails, documents and spreadsheets, and hands over uncertain matters to a human. A prototype for 20-100 cases that your team has already handled costs €0. You pay the other half of the price when the system reaches your goal.

Questions

  • How do you automate the acceptance certificate workflow?

    Connect the place where signed certificates come back to the project and the billing person. The automation recognises the project and the scope, tells the signed document from drafts and passes it on.

  • Is an email rule enough?

    Yes, when certificates come back to one mailbox with one template and a project number. AI makes sense when clients send back documents with different names and layouts.

  • How much does certificate automation cost?

    At Syntalith from €3,000 net. With 150 certificates a month at 15 minutes of searching and passing on each, the payback is 2.9 months.

  • Does AI confirm the signature on a certificate?

    No. Recognising the image of a signature does not confirm that it is authentic. AI helps find and describe the document, and the people responsible judge what it means for billing.

Let's talk
