Upload your pricing (CSV)
If you offer more than a handful of treatments, a pricing CSV is the quickest way to give Costello an accurate, complete price list in one go. Once uploaded, Costello can quote any service a customer asks about — no guessing, no out-of-date numbers from your website.
You can do this during onboarding, or any time afterwards in the Files & documents part of the Knowledge page.
Before you start
Use the downloadable template. On the Files & documents step you'll see a Download template link — it gives you a CSV with the right columns already set up, so all you do is fill in your prices.
The columns
| Column | What goes here |
|---|---|
| Service name | The treatment as a customer would say it, e.g. "HydraFacial MD". |
| Price | The price, or a range like "£80–£150". |
| Duration | How long it takes, e.g. "45 mins". |
| Notes | Anything useful — "consultation required", "course of 3 available". |
Keep service names natural. Costello matches on meaning, so "Lip filler (0.5ml)" works better than an internal code like "LF05".
Uploading
On the Files & documents step, click Download template and open it in Excel, Numbers, or Google Sheets.
Add one row per service. Leave a column blank if it doesn't apply — only Service name and Price are essential.
Save or export the file in CSV format (most spreadsheet apps have "Export as CSV" or "Save as .csv").
Drag the CSV into the Files & documents area, or click to browse. Costello reads it and adds your pricing to its knowledge.
Open the Playground and ask "how much is a [treatment]?" to confirm the price comes back correctly.
How Costello uses it
When a customer asks about a price, Costello looks up the matching row and quotes it. If you've given a range, it quotes the range and suggests the customer enquire for an exact figure. If you've added a note like "consultation required", Costello mentions that too before pointing them to your booking link.
If a treatment varies by area or session count, enter a range rather than a single price. Costello will quote it honestly instead of committing you to a number you can't honour.
Updating prices later
When your prices change, just edit your spreadsheet and re-upload the new CSV. The fresh file replaces the old pricing, and Costello retrains automatically — usually within a minute. There's no need to delete anything first.
It's worth re-uploading after any price review so customers are never quoted an old figure.
