Choose a WooCommerce developer by how they work, not only by what they have built. Ask how they scope the job, where they test, how they handle updates, what you will receive at the end and who looks after it afterwards. Clear, specific answers matter more than a long portfolio.
This guide is written for store owners and agencies hiring for custom work: a plugin, an integration, a checkout change or a rescue job. It applies whether you hire a freelancer, a studio or an agency partner. It is general advice; it is not a ranking of anyone.
First, write down what you need
A short brief saves money. Include what the store sells and how many orders it handles, the problem in plain words, what must not change (payment, tax, shipping rules, integrations), the deadline and why it matters, and who decides. If you cannot write the problem down, ask for a paid scoping session first, so the developer helps you define it before quoting for the build.
Questions to ask, and what a good answer sounds like
1. How will you scope and quote this?
Good: a written scope with what is included and what is not, an estimate with the assumptions behind it, and a way to handle changes. Be careful with a fixed price given after a two-line description, or with no written scope at all.
2. Where will you build and test it?
Good: on a staging copy of your store, never directly on the live site, with the change moved across in a planned way. Ask how they deal with data such as orders and customers on staging.
3. Do you change WooCommerce or other plugins directly?
Good: no. Customisations should live in your own plugin or child theme, using WooCommerce’s hooks and filters, so updates do not wipe them out. Editing another plugin’s files or WooCommerce core means every update becomes a risk.
4. How do you handle updates, and which WooCommerce features do you support?
Good: they test against current WooCommerce and WordPress versions, and they know about modern features: high-performance order storage (HPOS), the block checkout and the classic checkout. Ask which your store uses and how their code deals with them.
5. What do you do about security and data?
Good: they talk about escaping output, validating input, permission checks and nonces, and they avoid storing card data. For payments, a developer who says “we will make you PCI compliant” is promising something that depends on your whole setup, not on one plugin. Ask them to describe how card data is handled and what stays with the payment provider.
6. How will you test the work?
Good: a short test plan that covers the main paths (guest and logged-in customers, each payment method, shipping and tax cases, coupons) and the failure cases, and a test on a real browser and phone. Be wary of “it works on my machine”.
7. What will I receive at the end?
Good: the code in a repository you can access, short documentation of what was built and how to change it, and notes on settings and credentials. Ask who owns the code, and what happens if you part ways.
8. What happens after launch?
Good: a defined period for fixing defects, a clear price for ongoing support, and an answer to “who do I call when this breaks on a Saturday?”. Custom code needs looking after as WooCommerce and WordPress change.
9. How do you communicate?
Good: regular written updates, one point of contact and quick replies about blockers. Poor communication in the sales stage rarely improves during the project.
Warning signs
- No written scope, or a scope that cannot say what is excluded.
- Work done directly on the live store, with no backup plan.
- Edits to WooCommerce core or other plugins’ files.
- Promises of guaranteed results, such as a fixed speed improvement or compliance, before looking at your store.
- No access to the code or documentation at handover.
- Pressure to decide fast, or a price far below every other quote with no explanation.
- Vague answers about testing and about who supports the work later.
Check what they have actually built
- Ask for one or two examples that resemble your job, and what the developer personally did on them.
- Where it is possible, look at a plugin or public code they have published, and read the reviews and support replies on it.
- Ask a past client for a short reference, and be aware that testimonials describe one project each.
- Try a small paid first task before committing to a large build.
Get a baseline before they start
Before a developer touches your store, record how it looks today: a list of what is working, what is slow and what is misconfigured. Then you can tell whether the work improved things or made them worse. A free scan from the KODENZO Commerce Health plugin gives you a read-only snapshot of your store’s configuration and a score to compare against afterwards. It does not test your real payment methods and it is not a substitute for a developer’s review.
Frequently asked questions
Should I hire a freelancer or an agency?
Either can be right. A freelancer can be fast and personal but is one person; an agency spreads risk across a team but may cost more. What matters is the same list of answers above.
How much does a WooCommerce developer cost?
It depends on the work, the developer and the market. Rather than comparing hourly rates, compare scope, assumptions and what is included for support.
Do I need a developer for a small change?
Sometimes a plugin or a setting does the job. Ask a developer when the change touches checkout, payments, tax or an integration, because mistakes there cost money.
