T Tekin Works

Small, finished business software.

Most of these jobs are still run on a spreadsheet that one person understands and everybody else is afraid of. I build the finished replacement — narrow, done, and installed on your own domain. Every system below is live. Click into it and use it; there is no signup wall.

Working systems

Real data loaded. Log in with the demo account on each card.

Specialty subcontractors

Draw

Progress billing and lien waivers in one place. The G702 and continuation sheet carry forward from the last application, retainage calculates itself, and conditional and unconditional waivers are generated and tracked per party — so you know the draw is clean before you submit it.

GCs, property & facilities managers

Binder

Certificate of insurance tracking that reads the endorsements, not just the expiry date. See which vendors are actually compliant, which are about to lapse, and which certificate is missing the coverage your contract requires.

Public-works contractors

Prevail

Certified payroll for prevailing-wage jobs. Build compliant WH-347 reports from the hours you already track, catch classification and fringe errors before submission, and give the reviewing agency a portal instead of a mailbox.

Food producers & distributors

Lotpath

Lot traceability built for the day you actually need it. Record what came in, what went out and what it became — then produce a full trace in minutes instead of reconstructing it from paperwork during a recall.

Brands selling into retail

Recoup

Retail deduction recovery. Every chargeback in one queue with its backup documents, a running total of what has been written off by default, and the dispute packet assembled for you instead of rebuilt each time.

Digital product sellers

Postsale

A delivery portal for what you sell. Customers get one durable link to their files and licence keys instead of a buried email attachment, and updated versions reach every past buyer without a mailing list.

How buying one works

No subscription, no seat count, no lock-in.

Installed for you

Running on a domain you own, with your company details, your forms and your first projects already entered.

One-time price

Paid once, with a fixed scope written down before anything starts. Optional hosting afterwards if you want it.

Your data stays yours

It runs on your own instance. Export the whole database whenever you like, with or without me.

Tell me what you are still doing in a spreadsheet.

Send me the problem and roughly what it should do. You will get a fixed price and a delivery date back — usually within a day — and a clear answer if I am not the right fit.
