The Timeline for Building an Online Store: How Much Time You Actually Need
The typical timeline for a simple to mid-complexity online store depends on the project's scope, while more demanding projects with multiple integrations can take longer to build. The timeline is affected most by the project's complexity, the number of integrations needed, and how quickly the client approves each phase. A realistic schedule only takes shape once you know these three variables in advance.
In short:
Set the actual deadline only after a scope analysis; connections to business information systems, multiple payment methods, a large catalog, or multilingual support all extend the timeline.
Delays often come from missing descriptions, photos, and prices, and from slow approvals; one responsible point of contact and organized API access shorten the wait.
Prepare content, legal documents, your choice of payment and delivery providers, and access to their interfaces before populating the store, so development doesn't stall.
Before launch, the client and development team check orders, notifications, payments, connections, load, and security; the schedule should include time for fixing bugs and retesting.

The phases of building an online store (step by step)
Every project goes through the same sequence of phases — only their duration and depth differ. Understanding this sequence helps you set realistic expectations and know when you'll need to approve something.
The discovery phase lays the groundwork: we define the store's goals, target audiences, catalog scope, and the integrations needed. During this phase, we also check which mandatory information and legal elements the store needs to include, since online sales need to comply with mandatory disclosure and GDPR requirements. This is followed by architecture planning, where we define the site structure, order flow, and data model.
The design phase (UI/UX) delivers the visual identity and user journeys, while development produces the actual front-end and back-end code. After development come integrations with external systems, then testing, and finally launch, followed by a maintenance period.
Discovery and content preparation: goals, scope, legal compliance, and a rough timeline.
Planning and architecture: page structure, order flow, data model.
Design (UI/UX): visual identity, mockups, approval of the look before development.
Development: building the front-end and back-end of the store.
Integrations: connecting to payment systems, the warehouse, delivery.
Testing and launch: QA, UAT, go-live, and the move into maintenance.
Every phase ends with the client's approval, so how quickly they respond directly affects how fast the project moves into the next stage.
Typical timelines by project complexity
Timelines vary depending on how many features, integrations, and products a store includes. The ranges below are general estimates, since each phase affects the next, and a delay in one often carries forward.
A simple store (a smaller catalog, standard payments, no complex integrations): the timeline is typically shorter.
A mid-complexity store (multiple product categories, basic delivery-service integrations, custom design): the timeline depends on scope and integrations.
A demanding store (an ERP connection, multiple payment methods, a complex catalog, multilingual support): development can take longer.
The difference between these tiers isn't just the amount of work — it's the number of dependencies between phases. On more demanding projects, integrations often require coordination with external providers, which extends waiting periods independent of our own pace of work. That's why it's worth treating these estimates as a starting point, with the actual deadline only taking shape after the discovery phase, once we know the exact scope.
The factors that affect the timeline the most
Some project elements consistently cause delays, while others, if prepared in advance, substantially shorten the timeline.
Technical integrations: connections to ERP systems, payment providers, a warehouse, or courier services often require access to third-party APIs, which can take longer than developing the store itself. For payment system integration, it's essential that access credentials are ready from the start.
Preparing content and images: product descriptions, photos, and prices need to be ready before the store-population phase, otherwise launch gets pushed back.
How quickly the client decides: every phase waits on approval, so slow responses directly extend the whole project.
Quality of testing: insufficient testing before launch often means fixes after going live, which is more expensive and slower than thorough testing upfront.
Legal requirements: preparing terms and conditions and the data required by legislation needs to be aligned during the content-preparation phase already.
Pro tip: designate one responsible person on the client's side for all approvals, since coordinating between multiple people is the most common cause of delays.
Testing, launch, and go-live: what to include in the schedule before launch
Testing often isn't given enough time in the schedule, even though it's a phase that directly affects how well the store performs after launch. We distinguish between internal quality assurance (QA), carried out by the development team, and user acceptance testing (UAT), where the client tests the store themselves.
Before launch, you need to check functional operation (orders, notifications, payments), integration connectivity, site responsiveness under load, and basic security aspects. We recommend building a buffer into the schedule for fixing bugs and retesting after fixes.
Checkout deserves particular attention, since research from the Baymard Institute shows that reducing cognitive effort and auditing every field in the purchase flow reduces cart abandonment. You'll find more on practical usability testing in our overview of website usability testing methods.
A checklist for clients: how to speed up the project and reduce delays
The biggest factor affecting how fast a project moves is the client's preparation, even before development starts. The steps below help prevent the most common causes of delay.
Prepare your content following the agreed-upon template: gather product descriptions, photos, and prices before starting to populate the store.
Designate one point of contact to approve each phase, and agree on a maximum response time.
Decide in advance which payment and delivery services you want to use, and ensure access to the necessary APIs.
Prepare your legal documents and settings related to personal data protection before the testing phase.
Prepare test data and usage scenarios so the UAT phase can run without additional delays.
Pro tip: prepare content and legal documents in parallel with development, not only afterward, since these are tasks you can carry out independently of the technical side of the project.
The author's perspective: what most often extends the timeline
From experience managing projects, we've found delays are rarely caused by development itself — more often it's missing content or slow decision-making from the client. A clear phase schedule and a single contact channel for approvals are the two measures that contribute the most, in practice, to keeping a project on deadline. During the initial project analysis, clients get a rough duration estimate from us, along with a list of everything that needs to be prepared in advance.

How we help you keep the project on schedule
We start every project with a scope analysis, where we work together to set a realistic deadline based on your requirements and available content. Since we develop our own code and don't build on pre-made platforms, we can tailor integrations and features exactly to your needs, without the technical constraints of a third-party solution limiting you.
Our services that directly affect the speed and quality of delivery include:
Planning and building custom online stores.
Developing web applications for more demanding business processes.
Integrations with payment systems, warehouses, and delivery services.
Hosting, domain registration, and support and maintenance after launch.
An inquiry is followed by a brief introductory conversation, where we review your project's scope, give you a rough timeline estimate, and agree on next steps. If you'd like a concrete timeline for your store, check out our service overview and get in touch.
Frequently asked questions
How far in advance should a project start before the desired launch date?
For a simple to mid-complexity store, it's advisable to start early enough before your desired launch date. For more demanding projects with multiple integrations, build in extra buffer time, so there's room for testing and any necessary fixes.
Which step in the process most often causes delays?
The most common cause of delay is slow content preparation or slow phase approvals from the client. Technical integrations with payment or delivery systems can also extend the timeline if access to the necessary APIs isn't sorted out in time.
Is testing before launch really necessary if time is limited?
Yes, testing (QA and UAT) is an essential phase, since checkout best practices show that even minor mistakes in the purchase process can substantially reduce conversion. Cutting this phase short often means more expensive fixes after launch.
What do we, as the client, need to prepare so building the store doesn't stall?
Prepare your content, images, and product prices in advance, designate a responsible person for approvals, and decide on your payment and delivery providers. Sort out legal documents and privacy settings before the testing phase, so UAT isn't held up.
Does Moxy Web also help with legal compliance when building a store?
During the discovery phase, we check which mandatory information and legal elements the store needs to include, and build this into content preparation from the start. You'll receive the exact price and scope of this service after an analysis of your project.
