Subcontractor contract templates that ask the right questions

Santix has subcontract templates for 40 work packages, from excavation and formwork to tiling, lifts, scaffolding and crane hire. It asks for the missing terms (parties, scope, price, advance, payment period, retention, delay penalty and cap, duration, guarantee, insurance), flags critical points and produces a PDF draft. Uploading the signed PDF sets up reminders.

How do you draft a contract in Santix?

A four-step wizard: template, company, questions, review.

  1. Template: search the trade, such as tiling. The pricing model comes from the template and can be changed.
  2. Company: pick the subcontractor or add one. Coming from a selected bid, company and trade are filled in.
  3. Questions: grouped as parties, scope, price and payment, retention and taxes, duration and penalty, acceptance and guarantee, site and materials, technical terms and legal terms. Your company details and the subcontractor record fill what they can.
  4. Review: check the incomplete fields and the critical points, read the draft clause by clause and add your own clauses if needed.
  5. Save, share the PDF with your lawyer, then move it through review and approval.
  6. After signing, upload the signed PDF. Santix confirms and creates the reminders.

Drafts can be prepared offline and sync later; uploading the signed copy needs a connection.

What does the wizard ask?

A template holds about 50 variables. Some are required; others add a clause only when answered. In the excavation template the groups cover parties and their tax and social security numbers; project and scope; price model, unit, price excluding VAT, currency, advance, payment period, days to payment, pay-when-paid and price escalation; retention, guarantee letter, stamp duty, VAT withholding and multi-year status; start and end dates, penalty and cap, change limits and termination threshold; guarantee, defect period and insurance; materials, site power and water, scaffolding and accommodation; trade-specific technical terms; jurisdiction and copies. The draft has 21 headings.

What does "fill with the assistant" do?

Write the deal in your own words, for example "1.2 million TL excluding VAT, 10 percent advance, monthly payments, 1 per mille daily penalty capped at 10 percent", and AI extracts the values. Nothing is written until you choose which values to apply. It suggests the next three questions and flags risks such as a penalty without a cap or an unsecured advance. To add a clause the template lacks, write it yourself or give an instruction and the assistant drafts it in formal contract language for you to review. Without a connection the wizard works fully by hand. See AI assistance.

Which critical points are flagged?

Every template carries 8 to 11 warnings in three levels. Common ones: joint liability for the subcontractor's wages and social security, with a clearance letter at each payment; stamp duty at 9,48 per mille, due by the 26th of the following month; 5 % withholding on multi-year work; 4/10 VAT withholding; minimum labour checks before releasing retention; release conditions for retention; and delay penalties, commonly 1 per mille a day capped at 10 %. Others are trade-specific, such as cross-section surveys and disposal permits for excavation. Rates are general; confirm them with your accountant.

Example: a tiling labour contract

Model
Labour only
Price
₺1.200.000 excluding VAT
Advance
10 %, ₺120.000
Retention
5 %
Delay penalty
1 per mille a day, cap 10 %
Period, duration, guarantee
30 days; 1 Dec 2026 – 30 Apr 2027; 24 months

The penalty calculator shows ₺1.200 a day, reaching the ₺120.000 cap after 100 days, when it notes that a right to terminate arises. Stamp duty is ₺11.376.

Which dates are reminded?

For that contract signed on 20 November 2026, reminders go to the site manager, project manager and owner at 09:00 on: 26 December 2026 (stamp duty); each payment period close every 30 days from the start, with a social security clearance reminder three days before; 1 January 2027 (the job became multi-year, apply 5 % withholding); 16 April 2027 (14 days to completion); 30 April 2027 (provisional acceptance); and 30 April 2029 (guarantee over, final acceptance and retention release). Insurance and guarantee letter expiry dates add reminders 14 and 30 days before. Changing dates recalculates reminders not yet sent. Bank guarantees and policies are also tracked in document tracking.

Contract statuses

Draft, in review, approved, signed, in force, completed or terminated. The text of an approved or signed contract cannot be edited; changes need an addendum. A contract linked to a schedule task shows a delay penalty estimate when the task runs late; see schedule and Gantt.

Who can see a contract?

Project and site managers draft and edit; organisation admins can view; the owner has full access. A subcontractor invited and linked to its company sees only that company's contract. Field engineers, architects and viewers do not see contracts. See the subcontractor role.

What it does not do

The templates are awaiting lawyer review and are not legal advice. The app says so on every draft.

  • No e-signature; sign outside the app and attach the signed PDF.
  • It does not deduct penalties itself; you enter them in the progress payment.
  • It does not draft public works main contracts; it is for subcontracts and service agreements.

See the subcontract checklist for what to check before signing.

Why not copy last job's Word file?

A copied contract can keep the old subcontractor's name, an old price or a clause from another trade. In Santix every variable is a question, unanswered ones show up at review, the penalty is always asked with its cap, retention and advance flow into the budget, and signed dates become reminders.

Frequently asked questions

Are the templates legal advice?

No. They are awaiting lawyer review and every draft should be checked by your lawyer before signing.

Can contracts be e-signed in Santix?

No. Sign the draft PDF outside the app and attach the signed PDF to the contract record.

Does the assistant fill the contract for me?

It extracts values from your description and proposes them; you choose which to apply. The wizard also works fully by hand.

Can I edit a signed contract?

No. Approved and signed text is locked; prepare an addendum instead.

Can a subcontractor see other subcontractors' contracts?

No. A subcontractor linked to its company sees only that company's contract.
