ResDiary doesn’t publish its full pricing publicly — but based on customer reports and visible plans, expect roughly £109/month at entry, scaling to £200–£400+/month for larger venues and groups, with zero per-cover fees on top. That’s the headline difference vs OpenTable: ResDiary’s bill is predictable regardless of cover volume, which makes it the dominant choice among UK pubs and growing restaurant groups that don’t want their reservation system bill scaling with their success.
Below is the most accurate public picture we can assemble of ResDiary’s 2026 pricing, what each tier likely includes, and how the real cost compares to OpenTable and flat-fee alternatives at typical UK volumes.
ResDiary’s plans at a glance
ResDiary structures its pricing around a few tiers (exact names occasionally rebrand, but the structure is consistent):
| Plan tier | Approx. price | Typical fit |
|---|---|---|
| Entry | ~£109/month | Small single-location restaurants, cafés, neighbourhood pubs |
| Standard | ~£149–£199/month | Mid-size restaurants, busy gastropubs |
| Professional / Group | ~£200–£400+/month | Multi-location groups, high-volume venues |
| Enterprise | Custom | 10+ location groups, hotels with multiple F&B outlets |
No per-cover fees on any tier. This is the structural difference from OpenTable and TheFork.
Public pricing is not fully transparent on the ResDiary website — actual quotes come after a sales discussion. The ranges above are drawn from customer-reported pricing on review sites (G2, Capterra) and public mentions through 2026. Verify with ResDiary directly before committing.
What you actually pay vs OpenTable at UK volumes
Pricing transparency matters most when you compare effective costs. We modeled three typical UK volumes:
| Monthly covers | ResDiary (flat) | OpenTable Basic | OpenTable Core | Cheapest |
|---|---|---|---|---|
| 200 covers | ~£109 | £149 + ~£240 (£389) | £299 + £160 (£459) | ResDiary |
| 500 covers | ~£149 | £149 + ~£600 (£749) | £299 + £400 (£699) | ResDiary |
| 1,000 covers | ~£199 | £149 + ~£1,200 (£1,349) | £299 + £800 (£1,099) | ResDiary |
| 2,000 covers | ~£300 | £149 + ~£2,400 (£2,549) | £299 + £1,600 (£1,899) | ResDiary |
OpenTable’s per-cover fee structure (roughly £1.20 per network cover on Basic, £0.80 on Core) means total cost scales linearly with volume. ResDiary’s flat subscription tops out at a few hundred pounds even for high-volume operators.
For a busy pub doing 1,000 covers/month, ResDiary saves roughly £14,000/year vs OpenTable Basic.
This is the core economic case for ResDiary in the UK market.
Where ResDiary’s price is worth paying
Choose ResDiary when:
- You’re a UK-based mid-size restaurant or pub doing 200+ covers/month — flat-fee pricing compounds in your favour
- You manage 2+ locations and need group-level features (multi-site dashboards, shared guest profiles, group-level reporting)
- You need UK-native workflows — GBP-native pricing, VAT handling, integrations with UK POS systems
- Predictable monthly costs matter for your budgeting (no per-cover surprises)
- You want a vendor with deep UK track record — ResDiary has operated in the UK since 2010 and serves thousands of UK venues
Where ResDiary’s price isn’t worth paying
Skip ResDiary when:
- You run a very small operation (under 100 covers/month) — entry plan at £109/month is overkill; Resos free tier or SimpleERB (£39/month) handles you fine
- You depend heavily on a diner marketplace for new customer discovery — ResDiary doesn’t operate a consumer-facing marketplace like OpenTable.com or TheFork
- You need US-market features (Amex Resy integration, OpenTable network access in major US cities) — ResDiary’s strength is the UK and Commonwealth markets
- You want fully transparent self-serve pricing before talking to sales

Cheaper UK alternatives at the same feature depth
| Platform | Starting price | Cover fees | When to choose |
|---|---|---|---|
| Resos | Free (then £19/month) | None | Smallest restaurants, commission-free, very fast setup |
| SimpleERB | £39/month | None | Tiniest independents that need only basic reservations |
| ResDiary | ~£109/month | None | Mid-size + pub groups wanting UK-native enterprise features |
| OpenTable Basic | £149/month | £0.20–£1.20/cover | Restaurants where OpenTable network discovery actually drives bookings |
| TheFork Manager | Commission-based | Per-cover commission | European tourist-driven discovery |
The cleanest decision tree:
- Under 100 covers/month → Resos free tier or SimpleERB
- 100–500 covers/month → ResDiary or Resos Plus/Unlimited
