One ERP for your Bath hotel and spa, not three apps fighting over the same Saturday
A custom ERP (Enterprise Resource Planning) for a Bath hospitality group runs £70,000 to £180,000 and ships in 5 to 9 months. You build instead of buying NetSuite, SAP, or Odoo when one Georgian townhouse hotel, its treatment rooms, and a small events team all touch the same guest on the same weekend, and no single off-the-shelf schema can hold room nights, spa slots, and covers without a spreadsheet sitting in the middle.
You run a boutique hotel in the listed centre with a spa downstairs and a restaurant that fills on Jane Austen Festival weekends. NetSuite and SAP were built for distribution and manufacturing, so they treat a room night, a 50 minute massage, and a tasting-menu cover as three unrelated transactions, and your team stitches them together by hand every Monday.
Odoo gets closer, but its hospitality modules assume a chain layout, not a single property where the same guest books a suite, a couples treatment, and a table in one visit. The result is the double-booked treatment slot you already know too well, because bookings, treatments, and rotas live in three apps that never agree.
The fix: ERP built for Bath, not rented
A custom ERP models one Bath guest across rooms, treatment rooms, and covers in a single record, so a Saturday booking checks therapist availability before it confirms. It ties into your booking system, your till, and a VAT-ready ledger instead of forcing three exports into one weekly spreadsheet nobody trusts.

How long it takes, phase by phase
Exactly what you get
A working ERP that treats one guest as one record across your rooms, spa, and restaurant, hosted on infrastructure you control, with the source code and documentation handed over. You get an admin console for front-desk and spa managers, reporting that closes the month without an Excel step, and integrations wired to your card terminals and accounting tool. You also get a staging environment so you can rehearse a festival-weekend surge before it hits the live system.
How to choose a developer in Bath
Look for a team that has shipped hospitality software, not just brochure sites, and ask to speak to a client running rooms and treatments together. A Bath build lives or dies on the messy details: therapist skills, room turnaround, tronc splits, peak-season load, so the right partner interrogates those before quoting. Favour a UK-based team that understands VAT and HMRC Making Tax Digital, and insist on a paid discovery, a fixed scope, and clear code ownership before the full build. Adjacent systems worth scoping together are a BI (Business Intelligence) dashboard and HR (Human Resources) and rota tooling.
- One guest record spanning rooms, spa treatments, and restaurant covers, so nobody double-sells a therapist
- A month-end close that reconciles rooms, spa, and F&B automatically instead of three Monday-morning exports
- Availability logic that respects treatment-room turnaround and therapist skills, not just an open diary slot
- Software that feels as considered as a Royal Crescent address, which your kind of guest actually notices
- Capacity planning built for festival and Christmas-market surges rather than an average Tuesday
- A custom ERP costs more up front than a NetSuite or Odoo subscription and takes months, not a weekend, to go live
- You own the roadmap, so someone on your side has to make decisions instead of accepting a vendor default
- Migrating years of PMS and spa history is fiddly and where most of the project risk sits
- If your operation is genuinely one simple revenue line, a well-configured off-the-shelf tool may be enough
- !They demo a generic hotel ERP without asking how your spa rooms and therapists are scheduled. Ask them to walk a Saturday double-booking scenario end to end
- !No plan for migrating your PMS and treatment history. Ask exactly how past bookings and folios move across
- !They skip a fixed discovery phase. Ask for a paid discovery with a written scope before any build quote
- !Vague on code ownership. Ask in writing that you own the repository and all IP on final payment
- !One developer and no backup. Ask who covers a peak-weekend outage in August
Most Bath teams pricing ERP end up comparing notes on internal tools, shopify, inventory management too; the systems share one data spine. Weighing options across the region?

Frequently asked questions
What does a custom ERP cost for a Bath boutique hotel and spa?
In our delivery experience a custom ERP for a Bath hospitality group runs £70,000 to £180,000 depending on how many venues and revenue lines it spans. A single property with rooms and a spa usually lands in the £70,000 to £105,000 band and ships in five to six months.
Can one ERP handle hotel rooms, spa treatments, and a restaurant together?
Yes, and that is the main reason to build custom. Off-the-shelf systems like NetSuite or Odoo treat a room night, a treatment, and a cover as unrelated records, whereas a custom ERP hangs them off one guest folio, so a Saturday booking checks therapist availability before it confirms.
How do we migrate from NetSuite or Odoo without losing booking history?
A staged migration maps your existing guest, folio, and treatment records into the new schema, runs both systems in parallel for a short window, then reconciles totals before you switch the old tool off. Expect migration to be the fiddliest part of the project and to need clean exports from your current PMS and spa app.
Will a custom ERP handle UK VAT and Making Tax Digital?
Yes. A UK-focused build records VAT at the right rate per revenue line and keeps digital records that satisfy HMRC Making Tax Digital, either natively or by feeding a compatible tool like Xero or QuickBooks. Build that in from day one rather than bolting it on after launch.
Do we own the code if a Bath agency builds our ERP?
You should, and you should get it in writing. A reputable agency assigns the repository and all intellectual property to you on final payment, so you are never locked to one supplier and can hire anyone to maintain it later.
How long before a custom ERP is live for our next festival season?
Plan five to nine months from discovery to launch, so a build started in winter is realistic for the following autumn festival and Christmas-market peak. Rushing a hospitality ERP into a busy weekend is exactly how you recreate the double-booking problem you were solving.
Is it cheaper to keep paying for three separate apps?
Short term, yes, the subscriptions are lower than a build. In our experience a custom ERP tends to out-run stacked booking, spa, and rota subscriptions within around eighteen months once you count the staff hours lost to reconciliation and double-booking fixes.
Can you integrate our existing PMS instead of replacing everything?
Often yes. If your PMS works but your spa and rota tools do not talk to it, a custom layer can sit on top and unify the data rather than ripping out a system your team already knows. We decide what to keep and what to replace during discovery.
What ongoing maintenance does a custom hospitality ERP need?
Budget roughly 15 to 20 percent of the build cost a year for hosting, security updates, and small changes. A Bath spa and hotel operation keeps reworking its treatment menu and room mix, so plan for a support retainer rather than a one-off handover.

Who can build custom ERP software for a business in Bath?
Digital Heroes builds custom ERP software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, so an operator in Bath gets an assigned senior team rather than a local account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other ERP software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
