The real cost of skipping COGS
100 supplier-shop hauls a year × 25 items each × 60 seconds to type = ~41 hours/year. Painful, but survivable.
The expensive part is the HMRC enquiry without item-level records. HMRC's self-employed record-keeping rules require you to keep evidence of every business expense — and they don't accept “I sold roughly £20k of stuff.” They want every cost matched to every sale. Resellers without records typically pay an accountant five-figure sums to reconstruct from bank statements and eBay's archive, after the enquiry has already started.
One upload per supplier shop trip. Records done. Audit trail attached.
How AI Invoice Import works in 4 steps
- 1
Upload the receipt
Drag a PDF, JPG, PNG, or WebP into the Cost of Goods → AI Invoice Import zone. Up to 10MB per file. Multiple files in one go is fine.
- 2
Claude extracts every line item
Anthropic's Claude reads the receipt and returns structured data — supplier, invoice date, invoice number, total, VAT amount, supplier VAT number, payment method, and every product line with description, quantity, and unit price.
- 3
Auto-match against your eBay inventory
A second Claude call pairs each invoice line against your existing eBay listings — even when the supplier description (“Lexmoto LXR seat”) doesn't match the eBay title exactly (“LEXMOTO LXR 125 OEM seat assembly”). Each match comes with a confidence score so you know what to spot-check.
- 4
Confirm — COGS auto-fills
Review screen shows every match. Approve, override, or re-pair manually. On confirm, each matched inventory item gets cost per unit, supplier, purchase date, and a link back to the original receipt — accessible from the inventory page if HMRC ever asks.
What Claude extracts from every receipt
The full structured payload that lands in your dashboard from a single upload.
| Field | What it captures |
|---|---|
| Supplier | Charity shop, B&Q, Royal Mail, John Lewis — whoever's at the top of the receipt |
| Invoice date | Parsed as YYYY-MM-DD even from non-standard formats |
| Invoice number | The supplier's reference, where present |
| Total (gross) | Final amount paid in GBP |
| VAT amount | Total VAT charged, or null if there's none (charity shops, second-hand) |
| Supplier VAT number | GB123456789 format, or null if the supplier isn't registered |
| Payment method | Cash, card, bank transfer — or null if the receipt doesn't say |
| Items[] | Every product line: description, quantity, unit price |

Generic accounting OCR is built for clean B2B invoices — the kind a wholesaler emails you as a PDF. UK eBay resellers don't get those most of the time. They get charity-shop till receipts on thermal paper, car-boot scribbles on the back of a bag, eBay-purchase confirmations, Facebook Marketplace text-message screenshots.
The Claude prompt is explicitly tuned for that — vague descriptions, missing fields, no VAT, handwriting. Confidence score per match tells you what to spot-check. Generic OCR returns garbage on these inputs; DashVue returns a usable extraction with the “review needed” flags in the right places.
Audit-ready paper trail
The original receipt is kept on every imported item.
On every inventory row that came from an upload, DashVue stores the original PDF or photo, the supplier name, the purchase date, and the unit cost. HMRC requires self-employed traders to keep records for at least 5 years after the 31 January submission deadline; with DashVue every receipt is one click away from any inventory row for the full retention period. The full extraction history is also kept — including line-by-line reviews you accepted or overrode — so you have a defensible record of how the cost was assigned.
Optional AI add-on
AI Invoice Import runs on DashVue’s optional AI add-on — packs of AI actions you can add to any plan (AI Lite £9, AI Pro £19 or AI Elite £29 a month; every account gets 250 free AI actions to try it). Prefer to do it by hand? You can track COGS manually on the Item Costs page on any plan — flat rate, percentage, or per-item.
What AI Invoice Import doesn't do
Honest list, so you know what you're buying.
- It doesn't pull invoices from your inbox. Manual upload only — drag the PDF or photo in.
- It doesn't sync with Xero / QuickBooks / FreeAgent. The extracted data lives in DashVue.
- It doesn't file your VAT or self-assessment. This is data-entry automation, not tax filing.
- It isn't 100% accurate on handwritten receipts. The confidence score per match exists for a reason — review the “needs review” rows before confirming.
- It doesn't process bank statements as a feed. Single-file uploads only.
