WDI Billing vs Bullet: Which Is Right for Your Irish Business?
If you've been comparing WDI Billing vs Bullet, you're probably a sole trader or small business owner who wants invoicing that doesn't fight you - and you've likely already heard that Bullet built its name on exactly that: fast, phone-friendly invoicing for Irish tradespeople and freelancers. It's a fair reputation. But "quick to send an invoice" and "ready when Revenue or your accountant come asking questions" are two different jobs, and they call for two different kinds of software.
This page is a straight, feature-by-feature look at where Bullet earns its following, where WDI Billing takes a different approach, and which one fits your business better - particularly if euro-native billing, GDPR data residency, and a proper VAT3 workflow matter to you as much as speed does.
The short version
Bullet is built for speed and simplicity: raise an invoice from your phone in a couple of taps, log an expense on the go, done. It's a genuinely good fit for tradespeople and small operators who mostly need to bill and move on. WDI Billing starts from the same place - simple invoicing in euro, no fuss - but adds a structured path to VAT3, ROS-ready records, clean accountant access, and a clear stance on where your data lives and who can see it. If invoicing is 90% of your problem, either can work. If VAT compliance, accountant collaboration, or data control are part of the picture too, that's where the two products pull apart.
Where Bullet does well
To be fair to Bullet: it's popular with Irish sole traders precisely because it doesn't overcomplicate the basics. If your business is one person, one van, and a handful of invoices a week, a lightweight mobile-first tool like Bullet removes friction that heavier accounting software adds unnecessarily. That's a real strength, and we won't pretend otherwise.
Where WDI Billing takes a different approach
Euro-native billing, built for Ireland
Every invoice, quote, and report in WDI Billing runs in euro from day one - no currency conversion settings, no exchange-rate quirks creeping into your books because a template was built for a different market. If you've ever been burned by accounting software that treats Ireland as an afterthought, this is the baseline we start from, not an add-on.
Three modes: Records, Prepare, File
WDI Billing separates what happens automatically from what happens only when you say so. Records mode keeps your invoices, receipts, and bank transactions organised. Prepare mode - our default - gets your VAT3 return ready to review, but nothing is transmitted anywhere until you actively press file. File mode is the one deliberate step where your ROS-ready VAT3 actually goes to Revenue. Nothing streams to the tax authority in the background. That distinction matters if you want to understand your numbers before they become official.
GDPR and EU data residency, stated plainly
Irish business owners ask about data residency more than owners in most markets - and rightly so. WDI Billing is built around GDPR-aligned storage and a clear answer to "where does my data actually sit," rather than a vague reassurance buried in a privacy policy nobody reads.
Accountant access without losing control
WDI Billing supports break-glass style accountant access: your accountant or advisor can be invited in to see exactly what they need, when they need it, without you handing over the keys to everything permanently. That's a meaningfully different model from an all-or-nothing shared login.
Clean exports, no lock-in
Your data should leave as easily as it arrived. WDI Billing supports clean exports so your books stay genuinely yours, not hostage to one vendor's format - a principle that matters most the day you decide to switch accountants, or software.
No per-invoice fees
Some lightweight invoicing tools charge per invoice or per client once you scale past a free tier. WDI Billing doesn't meter you by the invoice - send as many as your business needs.

What switching from Bullet actually looks like
Owners who move from Bullet to WDI Billing tend to describe the same trigger point: invoicing was never the problem, but VAT3 season or a first proper conversation with an accountant exposed a gap. Maybe it was chasing down receipts that never made it into the app, or a back-and-forth with an accountant who needed a full export and got a partial one. WDI Billing is built so that gap doesn't open up in the first place - your invoices, receipts, and bank activity live in one place from day one, in Records mode, so there's nothing to reconstruct later.
The move itself is deliberately low-friction. Bring across your customer list, your invoice history, and your outstanding balances, and you're invoicing in euro on WDI Billing the same day. Nothing about switching should feel like starting over - and if you ever decide to switch again, your data leaves just as cleanly as it arrived, because clean exports aren't a feature we bolted on, they're a stated principle.
VAT3 is where the two products really diverge
Fast mobile invoicing solves the sending half of running a business. It doesn't solve the return half. When VAT3 season arrives, the question isn't "can I see my invoices" - it's "can I trust the numbers Revenue is about to receive, and did I get to check them first." WDI Billing's Prepare mode exists specifically for that moment: your VAT3 return is assembled and ready to review, line by line, before anything goes near ROS. You press file when you're satisfied, not before. That's a meaningfully different promise from an app that treats VAT as a bolt-on report generated after the fact.
For sole traders and small Ltds who file their own VAT3, or who want to hand their accountant something genuinely ROS-ready rather than a spreadsheet reconstruction, this is usually the deciding factor over Bullet - not because Bullet does invoicing badly, but because it wasn't built to carry you through to the return.
