Shopping feeds hidden costs live in data work, not invoices

What to take away

The hidden costs of shopping feeds sit in data workcatalogue cleanup, disapproval handling, consent checks and claim evidence.
Assume someone spends part of every week inside the feed platform, because data errors recur.
Personal information in a customer list brings UK GDPR duties, so treat data handling as a legal cost line.
Write your assumptions down before you commit budget, then review them every quarter.

A worked example for a shop turning over £750,000 a year reaches about £20,824 in hidden feed costs.
All figures are illustrative. Each line carries a typical monthly low to high range, set by your turnover, pay rates and catalogue size.

What counts as a cost line

This list covers recurring cost lines after a feed programme goes live. Each should appear in an invoice, a timesheet or a written scope of work.

1. Catalogue data cleanup

Feed quality follows catalogue quality. Empty GTINs, size charts stored in a PDF, and titles cut short all create work. Someone has to fix the source data rather than the export. That task returns every time a range changes, which for many shops means monthly.

Typical range: 2 to 8 hours a month, about £32 to £200 at £16 to £25 an hour.

2. Disapprovals and feed troubleshooting

Merchant Centre's help page on common issues in Merchant Centre treats most problems as data errors with a fix. Diagnosis is straightforward; the cost is the person doing it. Disapproved items earn nothing while they sit unresolved.

Typical range: 1 to 6 hours a month, plus lost sales.

3. Consent and personal data

If you upload customer lists or match audiences, you are handling personal information. The ICO's guidance on personal information under the UK GDPR is the definition to build against. Consent records, retention rules and deletion routines all take staff time.

Typical range: 1 to 4 hours a month.

4. Advertising claim checks

Titles and descriptions often carry claims about being the best seller, or about health and environmental benefits. Each claim needs evidence before it goes live, and evidence takes time to assemble. The ASA and CAP publish research on advertising effectiveness and compliance that is worth reading before you write claim rules into a feed template.

Typical range: 1 to 3 hours per claim.

5. Agency and freelancer scope creep

A retainer rarely covers everything. Extra feeds, new markets and peak-season checks often sit outside the agreed scope, and each one turns into a change request. Ask for the scope in writing, with a rate for additional work.

Typical range: £100 to £500 a month in change requests.

6. Reporting and reconciliation

Feeds touch several systems: the shop platform, the feed tool and the ad account. Reconciling orders across them takes time each month, and mismatched numbers create meetings. A simple monthly check beats a quarterly argument.

Typical range: 2 to 6 hours a month.

7. Training and cover

Feeds rarely belong to one person for long. Holidays, sick leave and job changes all interrupt the routine. A short handover document and a named deputy cost little and prevent expensive gaps.

Typical range: 1 to 3 hours a month, plus handover writing.

The monthly lines

An England-based shop turns over £750,000 a year and pays Feed platform fees of £250 a month for each of two channels, so £500. A merchandiser spends six hours a week on data at £16 an hour, or £416 a month.

The agency retainer is £400, and occasional contractor work adds £350, giving a monthly total of £1,666. Every figure here is illustrative.

Why the yearly number differs

Twelve months at £1,666 is £19,992. Two peak months with an extra six hours of merchandiser time each add £832, taking the year to £20,824. Range changes and compliance queries push it higher, and peak trading brings supplier data changes on top. Before you build the spreadsheet, the shopping feeds budget template sets out the columns worth tracking.

Recording these lines in a budget or timesheet

Give each line its own row and its own code, so hours and invoices land in the same place every month.

Cost line	Budget entry	File with it
Catalogue cleanup	Hours per month	Timesheet code
Disapprovals	Hours per month	Fix log
Consent	Hours plus annual review	Consent records
Claim checks	Hours per claim	Evidence pack
Agency scope creep	Retainer plus change requests	Signed scope
Reporting	Hours per month	Reconciliation sheet
Training and cover	Hours plus handover writing	Handover document

Log hours weekly and note the pay rate used for each person. Where a supplier invoices the work, file the invoice against the same row so the two views can be compared, and review the rows each quarter against the last three months of actuals.

Common questions

Is the platform fee ever the biggest cost?

Not usually. Where source data is weak, the hours spent fixing it beat the licence fee. Shops with clean data and stable ranges often find the opposite.

Which line is easiest to reduce first?

Catalogue quality. Fixing attributes at source lowers disapproval rates, so the same team handles fewer repeat cases.

Do these rules differ across the UK?

Feed platform requirements and advertising codes apply across the UK. The ICO regulates data protection for the whole of the UK, so a single data policy covers every nation.

How often should the assumptions be reviewed?

Quarterly suits most shops, with an extra check before peak planning starts. Written assumptions make the budget easier to defend when costs move.
