Odoo treasury module or a separate tool: how to decide
What changes if you put treasury inside Odoo as a module or let a separate tool read your data. Real cost, who installs it, who uses it and what happens on every upgrade.
Sooner or later every small business running Odoo bumps into the same question. Do you install a treasury module inside Odoo, or do you pay for a separate tool that reads your data and shows you the cash? The decision rarely comes down to the sticker price. What really matters is fit: who installs it, who uses it every Monday morning, and how much risk you want to carry on your bookkeeping.
This guide walks through what each option typically delivers, puts numbers on it by business profile, and ends with the questions worth answering before paying anyone. If you are still trying to understand why Odoo does not show you the forecast you need, start with how to build a cash flow forecast from Odoo data.
What an Odoo treasury module typically does
A module lives inside your Odoo. It adds menus, fields and, when properly done, a dashboard with a forward cash view and a projected P&L. Because it runs on the same database, it reads invoices, payments and reconciliation without asking. Whatever shows up in treasury matches what you have in accounting.
What usually comes with it:
- One-off fee of €100 to €400, tied to a specific Odoo version.
- Someone with admin rights installs it, or your partner does. Install plus training plus small adjustments rarely stays below a few hundred extra.
- Each annual Odoo release needs its own module upgrade: you wait for the author and you pay for it. On Odoo Online you cannot install third-party apps on any plan: you need Odoo.sh or your own server. Connecting a tool that only reads your Odoo data from the outside does work, but it requires the Custom plan.
It fits when the company has a technical team or a trusted partner and lives inside Odoo all day.
What a separate tool that reads Odoo does
A separate tool is another product, with its own login and its own screen. It connects to your Odoo, pulls the data (invoices with due dates, payments, bank statements, accounts) and presents it in a layout built for cash management. It installs nothing in Odoo, touches no journal entries, and plays no role in your accounting.
Usually included:
- Monthly subscription, typically €30 to €250 a month by size and features. Mid-market solutions usually start at a few hundred euros a month, plus onboarding; corporate suites run tens of thousands a year.
- Quick setup, no consultant. Create a user in Odoo that can only view the accounts and connect the tool.
- Upgrades are on the vendor.
- It cannot write to Odoo, so it cannot break your books. In exchange, it will not pay suppliers or post entries for you.
The right fit when the person running treasury is not the same person using Odoo every day. Classic case: the owner wants a 13-week view without learning Odoo, while admin keeps working inside Odoo as before.
Real cost over three years, not just the sticker
The usual mistake is to compare a one-off €300 against €60 a month and move on. The real cost has three pockets.
| Item | Odoo module | Separate tool |
|---|---|---|
| Licence or fee | €100-400, once | €30-250/month per plan |
| Install and training | 0 if DIY, a few hundred with partner | Usually included in the fee |
| Version upgrade | New payment every 1-2 years | Included |
| Hosting | Only on Odoo.sh or self-hosted; Odoo Online rules it out | Needs the Custom plan on Odoo Online for the connection |
| Your hours per month | More: you tune it and keep it alive | Less: the vendor does |
For a small business with one company and a healthy Odoo, a module can be cheap in year one. Add two things, one Odoo upgrade and a second legal entity, and the balance shifts. For a wider price picture, read the cost of cash flow software for small business and what each tier includes.
Who installs it and who will actually use it
The question that decides the most and gets asked the least. A module needs a functional or technical administrator; if that person is not in-house, you buy the hours and every upgrade passes through them. A separate tool can be set up by a careful finance lead with no Odoo tweaks.
And, above all, who will use it. A module lives inside Odoo: to open the treasury view you log into Odoo and accept its menus. A separate tool is a single screen built for someone who does not want to learn Odoo. If the person meant to review cash every Monday does not open Odoo today, a module will be opened three times and forgotten. If you are still unsure how your edition shapes this, read first the split between Odoo Community and Enterprise for cash management.
Accounting risk, alerts, group view and upgrades
Four things that rarely show up in the brochure but shape day-to-day life.
- Accounting risk. A module writes in your database, can modify views and, with enough permissions, create journal entries. A bug or a sloppy upgrade can translate into shifted due dates or balances that stop matching. An external tool that only reads your data cannot write to Odoo and cannot break anything.
- Email alerts when cash drops below a threshold you set. Few modules include them; most separate tools do.
- Multiple companies with a group view and intercompany flows netted off, so an invoice from one entity to another does not inflate collections and payments. Odoo consolidates by adding up; cleaning the intercompany side is on whoever builds the report.
- Version upgrades. If your Odoo moves between major versions every 1 to 2 years, each installed module is a piece someone has to move. An external tool does not care.
Kashbi, for example, reads Odoo without touching it, offers a group view with intercompany flows separated, and sends alerts by email.
Decision table by company profile
| Profile | Fits better | Why |
|---|---|---|
| 5-15 people, one company, self-hosted Odoo Community | Installed module | Technical team on hand, low risk, pay once every 1-2 years |
| 20-80 people, Odoo partner, admin team in-house | Depends on who watches cash | Admin watching: module. Owner or FD watching: separate tool |
| Group with 2-5 companies on Odoo Enterprise | Separate tool | Group view, intercompany flows and painless upgrades |
| Odoo Online on a Standard plan | Neither works | Standard allows no module installs and no external connections; confirm the plan first |
| Mid-upgrade period | Wait and use a separate tool | Adding a module right before an upgrade is asking for trouble |
Questions to answer before paying
- Who will open the treasury screen every Monday? Do they already log into Odoo?
- How many legal entities do you run? Do they invoice each other?
- What Odoo plan are you on, and what does it allow you to install?
- When is the next upgrade and who will handle it?
- What if the module stops being maintained or the tool raises prices?
- Can you trial it before committing to a year?
Three clear answers and the choice falls on its own.
Frequently asked questions
Will an Odoo treasury module give me a 13-week forecast?
Some will, some will not. Community modules often add listings and small dashboards; paid ones go further. Before buying, ask for a demo on your own data and check for the weekly view, scenarios and alerts. If the vendor cannot show it, they do not have it.
If I use an external tool, do I need to change anything in Odoo?
Usually only to create a user that can only view the data and, on Odoo Online, confirm that your plan allows external connections. There is no module to install, no view to tweak and no change to your accounts.
What happens to my treasury view if I upgrade Odoo?
With an installed module, you wait for the author to release the new version and you pay for it, or you migrate it yourself.
Can I use a module and a tool at the same time?
Yes, though it rarely pays off. The usual pattern is to keep operations inside Odoo (invoicing, collecting, reconciliation) and use a separate tool for the cash view and owner alerts. Two layers with clear roles work better than one trying to do everything.
