Usage meter
What is an AI credit? How AI usage is counted.
One credit is one piece of AI writing, such as a drafted answer. Each plan includes a number every month. Reading a tender document costs 3 credits for every 10 pages, rounded up. Searching, scoring, exports and sums are free.
Unused monthly plan credits do not roll over. Bought credits never expire. A generation that fails is never charged.
Need more credits?
Three options, each one your choice. Nothing extra is charged unless you set it up.
-
Credit packs
Packs of 100, 500 or 1,000 credits for £10, £50 or £100. They never expire.
-
Auto reload
Buys a pack for you when you run low, up to a monthly limit you set.
-
Pay as you go
Off unless you switch it on. Then 10p a credit, with a cap you choose.
Nothing extra is charged unless you set it up. Active bids and contracts are not metered against credits.

Bids are not metered, which is why that row reads unlimited on every plan. The meter is AI credits, and the number each plan includes is the row below it.
How AI credits are counted
What each plan includes
| Plan | AI credits a month |
|---|---|
| Starter | 200 |
| Pro | 750 |
| Portfolio | 3,000 |
These are the numbers the platform enforces. Bids, contracts, seats within your plan, exports and every deterministic calculation are not metered against them. Re-drafting the same answer is free for the first three re-drafts each month. The fourth costs one credit. A generation that fails is not charged.
Reading a tender document is charged by page
Uploading a tender document and extracting its requirements costs 3 credits per 10 pages, rounded up. A 10 page invitation to tender costs 3 credits. Here is what counts as a page:
| Document | One page is | Example |
|---|---|---|
| One page | 10-page tender document (ITT) = 3 credits | |
| PowerPoint | One slide | 12-slide briefing = 6 credits |
| Word or plain text | The whole document | Response template = 3 credits |
| Spreadsheet (Excel or CSV) | 50 rows of a sheet, rounded up and added across sheets | 5,000-row pricing schedule = 100 pages = 30 credits |
Why spreadsheets are counted by rows, not by sheets
A sheet is not a page. A 5,000 row pricing schedule on one Excel sheet holds roughly 17 times the text of a 10 page PDF. The AI work grows with how much text there is to read. Counting that as one page would charge the same for 17 times the work, so we count 50 rows as one page instead. CSV files are counted exactly like Excel files. We only count the rows we actually read, a sheet we read is never counted as nothing, and a generation that fails is not charged at all.

What happens when my AI credits run out?
Your monthly allowance is spent first, then any credits you have bought. After that, three options keep you going, and each one is your choice. Credit packs of 100, 500 or 1,000 credits cost £10, £50 or £100 and never expire. Auto reload buys a pack for you when you run low, up to a monthly limit you set. Pay as you go is off unless you switch it on, and then bills 10p a credit up to a cap you choose. With none of these on, AI generation stops until the month resets, so you are never billed beyond your plan without agreeing to it. Everything we calculate rather than generate keeps working, and a generation that fails is not charged.
Can I add more people?
Yes. Velstrian Bid Pro and Velstrian Buy Pro allow extra seats for £45 a month each, or £486 a year. Velstrian Bid Portfolio includes 10 users, with more available by arrangement.
Can I switch plans mid-cycle?
Yes. You can upgrade, downgrade or cancel at any time from the billing dashboard, and changes are pro rated and applied immediately. One limit is enforced rather than advisory: if you have already used more AI credits this month than the plan you are moving down to includes, the downgrade is held until your credits reset.
Are there any hidden setup fees?
No. There are no setup, implementation or training fees on any plan. The only charges beyond your plan are ones you choose: extra user seats, a credit pack, auto reload up to a monthly limit you set, or pay as you go at 10p a credit if you switch it on.
How do I pay?
All major credit and debit cards, through Stripe. Buyer Portfolio can also be paid by invoice on 30 days with a PO number, at the same price. Talk to us about invoice billing on any other plan.
What payment methods do you accept?
All major credit and debit cards, through Stripe. Buyer Portfolio can also be paid by invoice on 30 days with a PO number, at the same price. Talk to us about invoice billing on any other plan.
Is it only for public sector tenders?
No. Velstrian Bid and Velstrian Buy work for public and private sector tenders, RFPs, RFIs, PQQs and requests for quotes. Public tenders arrive from official feeds, and private documents can be uploaded directly.
How do I get access?
Choose a plan and select Start now. You create your account, pay by card through Stripe, and start straight away. There is nothing to request first. If you would like a walk through before you start, book a demo.
Do you price for large organisations?
Yes. Portfolio is £549 a month, or £5,929 a year, for 10 users and 3,000 AI credits a month, and adds the Integrations package. Single sign-on via SAML 2.0 and SCIM user provisioning are included on every plan. Buy it by card and start today. Talk to us about contracts, custom terms or more than 10 users.
How is Velstrian Buy priced?
Buyer Pro is £299 a month, or £3,229 a year, with 5 users, 750 AI credits a month and 10 guest evaluators. Buyer Portfolio is £699 a month, or £7,549 a year, with 10 users, 3,000 AI credits a month and 25 guest evaluators. Annual prices are 10% off twelve months. Pay by card, or pay for Buyer Portfolio by invoice on 30 days with a PO number. Talk to us if you buy through a framework.
How are AI credits counted?
Each plan includes a monthly allowance: 200 credits on Starter, 750 on Pro and 3,000 on Portfolio, and Velstrian Buy carries 750 on Buyer Pro and 3,000 on Buyer Portfolio. One credit is one AI generation. Reading a tender document and extracting its requirements costs 3 credits per 10 pages, rounded up, so a 10-page tender document (ITT) costs 3 credits. A page is one PDF page, one PowerPoint slide, or a whole Word or text document. A spreadsheet is counted by rows rather than by sheets: 50 rows count as one page, so a 5,000-row pricing schedule on a single sheet counts as 100 pages, or 30 credits. Everything we calculate rather than generate is never charged and never capped, and a generation that fails is not charged.
Is there a free plan?
No. Velstrian Bid is a paid product. You can run the free Tender Compliance Matrix at any time with no account, and your first 7 days on Velstrian Bid are free. A card is needed to start, held securely by Stripe and never stored by us.
