Business Case — Working Notes

Working draft
Updated 26 May 2026 · Based on your round-1 answers

Reflecting back what you told me, what it implies for the project, and the funding shapes we'll have on the table for the owner conversation. Final figures and the formal proposal come once the blueprint is locked.

From you

What you told me

Volume & scale

Transactions per day
50–75 (busy vs quiet)
Average basket
£80–90
Live products (of 11,500 in Magnum)
~10,000 actually selling — only ~13% is dead stock
Sales-method split (payment)
~70% card, ~30% cash / bank transfer
Sale-type mix (barcode / weight / length / manual)
Not answered — to confirm next call

Credit accounts

Trade customers with credit
~150
Typical credit limit
£1,000 usual, up to £3,000–£4,000 for the biggest accounts
Credit transactions per week
Not answered — to confirm next call
Repayment pattern
Not answered — to confirm next call

Suppliers & staff

Suppliers
~20
Total staff
4
Computer-comfortable
~2 of 4
Pilot a new till in parallel?
Yes — confirmed

Hardware & connectivity

Receipt printer
Brother A4 office printer — not a thermal till printer (see note below)
Barcode scanner
Buying a new one — recommendation coming back to you
Internet
BT broadband + 4G backup
What this implies

Reading between the lines

Payment-method split makes the Dojo integration valuable

With ~70% of sales going through card, every one of those today involves a staff member manually typing the amount into the DNA terminal — roughly 90 manual amount-keys per day across both tills, every one carrying a typo / fraction risk. Replacing this with auto-amount push from the till to a Dojo terminal eliminates a whole class of "end-of-day mismatch" headaches.

Hardware finding worth flagging

Receipts on a Brother A4 office printer is unusual for a shop your size. Receipts are slow, expensive (full A4 sheets + ink), and look less professional than they could. We'll factor proper thermal receipt printers into the project so receipts go from ~minute-long prints to sub-second, and paper/ink spend drops dramatically.

Sizing call

This is a comfortably sized SMB — busy enough that till downtime hurts, small enough that we don't need enterprise-grade infrastructure. A modern web-based EPOS on a clean database, hosted on a single small server with daily backups, has more than enough headroom — including space for a second branch when you're ready.

The credit book is meaningful working capital

150 active credit accounts is a healthy amount of trade business. The current system makes that book harder to manage than it needs to be — every improvement to the credit module (statement, limits, repayments) is improvement to your cash flow.

For the owner conversation

Funding shapes we'll have on the table

Five realistic paths to fund the project. Each one is a different shape of commitment — the owners pick whichever fits their cash flow best. Specific figures land with the formal proposal once the scope is locked.

Option A

Milestone-based one-off payment

Standard agency model — paid in four chunks tied to delivery gates. Cleanest commercial relationship and the lowest total cost overall. Best fit if cash flow allows a meaningful first payment up front.

Option B

Lower upfront + monthly retainer

Roughly half the upfront commitment of Option A, balanced by a small monthly retainer that also covers hosting, support, and small ongoing improvements. Predictable monthly cost — easy to budget on the P&L.

Option C

POS-as-a-Service — single monthly fee, zero upfront

No capital outlay at all. A single monthly fee covers everything — build, hosting, support, hardware lease — for a fixed term, with full ownership transferring at the end. Easiest "yes" if cash is tight today.

Option D

External finance / business loan

We bill on milestones the same way as Option A; the owners borrow the build cost externally and repay their bank over 3–5 years. Many SME-friendly UK options exist (Funding Circle, iwoca, Tide, high-street banks). Your accountant may actively prefer this for tax reasons.

Option E

Pilot phase first, decide later

Lowest-risk on-ramp. We run a paid pilot phase (data audit + first till + credit module live on one till). You evaluate it for 30 days. If you continue, the pilot fee rolls into the full project price. If you don't, we stop and you keep the cleaned data. Smallest first commitment.

Still need

What we still need from you / the owners

None of these block the blueprint from being drafted — they just sharpen the proposal we put in front of the owners. Most are covered in the Round 2 questions.

  1. Budget ceiling — even a "definitely not above £X" is useful, so we don't propose something that's a non-starter.
  2. Timeline pressure — is there a specific reason to be on the new system in 3 months vs 9? (Stock-take, tax year, new branch lease, etc.)
  3. Second-branch reality check — is it actively planned, or aspirational? Affects how much branch-readiness we bake in on day one.
  4. Credit transactions per week — the round-1 70/30 answer was the payment-method split, so we still need the actual credit-transaction volume number.
  5. Sale-type mix (barcode / weight / length / manual) and credit repayment pattern — small but they shape the till UX.
  6. Round 2 questions — the new short batch is in the portal, tagged by effort so they're easy to chip through.
