A practical guide before you start
Planning your project
Start by writing down the one or two outcomes that would make the project a success. Agree who on your side will make decisions, so questions are answered quickly. List the systems, accounts and data the work will touch before anything begins. A short discovery phase usually saves time later by surfacing risks early. Set a realistic budget range and share it, so the proposal can be shaped around it. Break larger goals into phases, each with its own clear result. Decide how often you want updates and in what format. Plan for training and handover from the start rather than at the end.
Questions worth asking any provider
- Who will actually do the work, and how experienced are they?
- What exactly is included in the price, and what would cost extra?
- How will progress be measured and reported?
- Who owns the accounts, code and content once the project ends?
- What happens if priorities change partway through?
- How are security, privacy and access to your data handled?
- Can you speak with the people who will lead the project before you commit?
Measuring success
Agree a small set of measures at the start and track them consistently. Look at trends over several weeks rather than reacting to a single day. Connect results to enquiries, sales or hours saved wherever possible. Review what worked and what did not at the end of every phase. Share results with your wider team so everyone understands the progress. Use what you learn to shape the next phase rather than repeating the same plan.
What to prepare
Gather examples of competitors or businesses you admire, and note what you like about them. Collect logins and admin access for the tools involved, shared through a secure password manager. Pull together any previous reports, briefs or research so nothing is repeated. Think about the customer questions your team hears most often. Note any deadlines tied to launches, seasons or events. Identify the internal teams who should be consulted along the way.
Common challenges we solve
- Projects that stalled because nobody owned the next step.
- Tools that do not talk to each other, so staff copy data by hand.
- Reports that show activity but not results.
- Websites and systems that are slow, dated or hard to update.
- Suppliers who disappeared after launch, leaving no documentation.
- Budgets spent on work that never connected to business goals.
How engagements are structured
Most projects begin with a short discovery stage to confirm goals, scope and priorities. A written proposal then sets out deliverables, timelines, responsibilities and costs. Work is delivered in clear phases, each reviewed with you before the next begins. You see progress through regular check-ins and a shared project board. Changes to scope are agreed in writing before any extra work starts. Every phase closes with a summary of what was delivered and what comes next.
Choosing the right level of support
Some clients need a one-off project with a clear start and finish. Others prefer a monthly retainer with steady, ongoing improvements. Larger organisations often combine a core project with on-call support for their team. Whichever model you choose, the scope and costs are agreed in advance. You can move between models as your priorities and budget change.
After launch
We monitor performance closely in the first weeks and fix issues quickly.
