How does a subcontractor join?
The main contractor creates an invite code for the subcontractor's manager or foreman on the team screen. When the invite is created the role is set to "Taşeron" (subcontractor) and the person is linked to their firm, for example "Akdeniz Tesisat". The code has 8 characters, is valid for 14 days and is single-use by default. The subcontractor installs the app, creates their own account, enters the code and joins the project.
The subcontractor does not buy a subscription; they use one of the inviting firm's seats. If three people from the same subcontractor join, that is three invites and three seats. The link to the firm matters: it is what makes the firm's contract and documents visible to them.
What does a subcontractor's day look like in Santix?
On a phone the first screen is the overview, which for a subcontractor lists the work assigned to them. The example below follows a tiling subcontractor on our sample project "Ataşehir Blok B" (ATB-02). The app interface is Turkish, so labels are given in Turkish with a translation.
Morning: work is assigned
On the site walk the site manager sees missing grout in bathroom Z-03, drops the pin "#14 Banyo seramik derzi eksik" on the drawing and assigns it to your firm with a Friday due date. Your phone gets a notification. Opening the pin shows the site manager's photo, voice note, due date, priority and the exact spot on the drawing. Tapping the room on the drawing opens its data sheet: net area 11.47 m², walls "Seramik 30×60", floor "Seramik 60×60". Nobody has to describe which bathroom on which floor.
Midday: you start, or you are stuck
When you start, set the pin to "Devam ediyor" (in progress). If you cannot continue because material has not arrived or the work before yours is unfinished, set it to "Engelli" (blocked) and write the reason as a comment; the site manager sees it as a separate status. For example: "The plumbing team has not closed the cistern outlet, the wall cannot be tiled." If the drawing does not answer a question, ask it as a comment; if it needs a design change, the site manager or field engineer raises a revision request.
Evening: the work is done
Take a photo, attach it to the pin and set the status to "Kontrol bekliyor" (awaiting inspection). The site manager or field engineer checks on the spot: if it is fine they mark it done and close it; if not, they comment and send it back to in progress. The closed pin stays as a handover record with its photo. With no signal in the basement, photos and status changes wait on the phone, the header shows something like "Çevrimdışı · 2 bekleyen" (offline, 2 pending) and they upload once the connection is back.
A problem you spotted
Subcontractors can open pins too. You can photograph and mark plaster damage left by the previous trade. You and the project team see the pin you opened; the site manager assigns it to the right person. It becomes a dated record that the damage was there before you.
What does a subcontractor see in contracts and documents?
Under "Sözleşmeler" (contracts) you can read your firm's contract: scope, price and currency, advance, payment period, payment terms, retention rate, daily delay penalty per mille and its cap, and warranty period. You cannot change it. If the signed PDF has been attached, you can open it.
Under "Evrak" (documents) you see documents linked to your firm: your workers' health and safety training certificates, medical reports, your firm's guarantee letter. A document close to expiry shows a badge such as "Yaklaşıyor · 12 gün sonra" (due in 12 days). Documents are added by the main contractor's team; you send new ones to the site manager.
In the schedule you see only tasks assigned to you or your firm. You can update progress on your own tasks; other tasks and the full critical path are not shown.
What can a subcontractor see and not see?
A subcontractor sees only records about themselves and can change only work assigned to them or opened by them. This is enforced in the database, not just on screen; another firm's record never reaches your phone.
| Module | Subcontractor's access |
|---|---|
| Drawings and room data | Read |
| Pins | Assigned to them and opened by them; status, photos, comments |
| Closing pins | Can move to awaiting inspection at most; cannot close |
| Schedule | Only tasks assigned to them or their firm |
| Contracts | Reads their own firm's contract only |
| Official documents | Only documents linked to their firm |
| Procurement and bid comparison | Hidden |
| Budget, payment amounts, payments | Hidden |
| Other subcontractors' work, contracts and documents | Hidden |
| Team and invites | Cannot create invites |
The progress payment calculation and amounts sit in the budget module, which is closed to subcontractors. Ask the firm's project manager or site manager about the status of your payment. The payment period and terms in your contract are visible to you.
What other roles see is on the roles and permissions page.
What is in it for the subcontractor?
The most concrete difference is that "was this done?" is tied to a dated record with photos. When the work was assigned, when it moved to awaiting inspection, and who closed it or sent it back are all in the pin's history.
| Subcontractor's problem | In Santix |
|---|---|
| Work is assigned verbally and the due date is disputed later | Assignment date and due date are written on the pin |
| "You didn't do it" with no way to prove otherwise | A photo-backed awaiting-inspection record and history |
| The previous trade's damage is left to you | A dated pin you opened yourself |
| Work is built from the wrong drawing | Everyone opens the same current version |
| Your items get lost among other firms' topics in WhatsApp | Only your work is listed |
How pins work is on drawing markup, and record keeping on site in the daily site report guide. What to check before signing is in the subcontract checklist.
What does Santix not do for a subcontractor?
Santix does not run the subcontractor's own business: your crew's timesheets, your own material orders and your own accounts are not kept in Santix. You cannot see your payment amount in the app. Santix currently runs on iPhone and iPad only; Android is in preparation. A subcontractor who wants to use Santix independently of a main contractor can open their own organisation and subscribe.
Frequently asked questions
Does a subcontractor have to pay to use Santix?
No separate subscription. The subcontractor joins the main contractor's subscription with an invite code and uses one of that firm's seats.
Can a subcontractor see the status of their progress payment in Santix?
No. Payment amounts are in the budget module, which is closed to subcontractors. They can read the payment period and terms in their own contract.
Can a subcontractor with an Android phone use it?
Santix currently runs only on iPhone and iPad. The Android version is in preparation.
What does a subcontractor do about a snag that is not assigned to them?
They can open a pin themselves. They and the project team see it, and the site manager assigns it to the right person. Pins assigned to other firms stay hidden from them.
Can a subcontractor close their own work?
No. A subcontractor can move work to awaiting inspection at most. Done and closed are set by the site manager, project manager or owner.
Can a subcontractor see other firms' bids?
No. The procurement and bid comparison section is not shown to subcontractors; neither competing bids nor the main contractor's estimate prices are visible.
Can several people from one firm join?
Yes. A separate invite code is created for each person, all linked to the same subcontractor firm, and each uses a seat.
