The work-to-cash system for South African service businesses
From first instruction to final payment. One system.
Stellvia Control is being built for South African service businesses to carry every job the whole way: capture the customer’s instruction, keep the work and proof together, check each requirement with AI, prepare the invoice, track the payment and hand your accountant a clean record.

Why jobs get stuck
The work is done. The money is stuck in between.
The job lives in one place, the invoice in another and the payment in a third. The PO, the photos, the signature and the customer’s rules end up across chats, inboxes and spreadsheets. That is where invoices come back and payments wait.
Illustrative example
Today
- The PO is buried in an email thread.
- Job photos sit in a team chat.
- Visit 3’s signature is still on paper.
- The invoice is missing the PO number.
- A payment screenshot is not money in the bank.
- Your accountant is still asking for documents.
With Stellvia Control
- PO-101-204 read and linked to the job.
- Photos and notes on the right visit.
- Visit 3’s signature requested and received.
- Invoice prepared with the PO reference and proof.
- Payment checked against bank evidence and allocated.
- A dated pack ready for your accountant.

AI checks. People decide.
AI flags the mismatch before the invoice goes out.
Stellvia is being designed to read purchase orders, job cards and signed documents, check them against each customer’s requirements and prepare the next step. You approve what matters, and manual work is always available.
- Beside the sourceEvery proposal sits next to the document it came from.
- The smallest fixA check names what is wrong and who can fix it.
- Your authorityIssuing, sending and payment decisions stay with your people.
Illustrative example · Planned assistance
- Customer reference
- PO-103-204
- Work
- Three service visits at R3,000 each
- Total
- R9,000
- Customer reference
- PO-103-240
- Work
- Three service visits at R3,000 each
- Total
- R9,000
The draft proposes PO-103-240; the purchase order says PO-103-204. The check stops the draft until the reference matches, then prepares it for your review.
No AI available? Enter the reference from the source yourself and run the same check.

Questions
Straight answers before you join.
When can I start using Stellvia Control?
Stellvia Control is in development. Join the launch list to hear when it launches. No launch date is promised yet.
Does Stellvia do my accounting?
Not yet. Built-in accounting is planned for a future Stellvia update. Until then, keep your accountant or accounting software, and Stellvia Control prepares a dated record with the sources they need.
Do I need accounting software?
No. In the planned accountant route, your accountant reviews a dated package, so you do not need your own accounting-software subscription.
Will AI make decisions for me?
No. AI is being designed to read, propose and check. Your people keep the authority to approve, issue, send and confirm payments, and manual work stays available.
What will it cost?
Owner is planned at R900, Team at R1,900 and Control at R4,000 a month, as full customer-payable prices with no VAT added. Yearly billing costs less than twelve monthly payments.
Who is it for?
South African service businesses that finish work before they invoice, especially when customers have purchase orders, sign-off rules or their own submission routes.
