Formation apps for London agents, accountants and law firms that set up companies.

Company formation app development London firms come to us for is rarely about the incorporation form itself. It is about everything around it: taking an overseas founder through identity checks, collecting proof of address for a registered office service, running customer due diligence, and keeping a director informed until the certificate of incorporation arrives. We build the client app, the staff workspace and the integrations that hold that work together.

London formation work has a strong international flavour. Many clients have never set foot in the UK, need a service address in the capital, and want a business bank account soon after incorporation. Your app should make that sequence feel orderly for them and auditable for your compliance team, without adding steps your staff then have to undo by hand.

What the app can include

Built around the way a London formation desk really runs.

A London formation business often sells several things at once: the incorporation, a registered office address in the capital, a service address for directors, mail scanning, a company secretarial package and sometimes an introduction to a bank or accountant. Each of those products carries its own checks and its own renewal date. Since the Economic Crime and Corporate Transparency Act changes, the identity side has also grown. New directors and people with significant control must have verified identities, and firms registered with Companies House as Authorised Corporate Service Providers can carry out that verification for clients. The features below are chosen for that reality, not for a generic signup form. We build only the ones your workflow needs in the first release and leave the rest on a written roadmap.

Explain your project
  • Overseas founder onboarding

    A guided flow for clients outside the UK: passport capture, proof of residential address, nationality and occupation, and a clear explanation of what a UK director must provide. Copy is written for people reading English as a second language, with progress saved so a founder in another time zone can finish later.

    Fewer incomplete applications sitting in your inbox.

  • ACSP identity verification workflow

    If your firm is registered as an Authorised Corporate Service Provider, the app records each identity check your staff perform, the documents relied on, who approved it and when the verification statement was made. Clients who prefer to verify directly with Companies House can record their personal code instead.

    Every verification has an owner and an evidence trail.

  • Customer due diligence and risk scoring

    Your Money Laundering Regulations procedures turned into screens: risk questions, source of funds prompts for higher risk cases, screening results from the provider you already use, and escalation to your nominated officer when something needs a second look.

    Due diligence happens before the filing, not after.

  • Registered office and service address products

    London address services sold and managed in the app: who the address belongs to, which documents support it, when it renews and what happens when a client stops paying. Clients can see their address details and the mail received against them.

    Address services stay tied to a checked, current client.

  • Mail scanning and forwarding

    Letters from HMRC, Companies House and banks logged on arrival, scanned, categorised and pushed to the client with a notification. Forwarding requests and collection notes are handled in the same thread so nothing is promised by email and forgotten.

    Clients read official post the day it lands.

  • Incorporation data capture

    Company name checks, SIC codes, share classes, subscribers, PSC details, the registered email address and the lawful purpose statement now required on incorporation, all validated before a member of staff reviews the application.

    Applications reach review complete and consistent.

  • Corporate shareholders and group structures

    London clients often form a UK subsidiary owned by a foreign parent, or a holding company above several trading entities. The app captures corporate subscribers, registration numbers abroad, the individuals who control them and the documents proving that chain, then shows the structure as a simple diagram your reviewer can check against the PSC entries before anything is filed.

    Ownership chains are understood before the register reflects them.

  • Package checkout

    Formation packages and add ons paid by card, Apple Pay or Google Pay, or by Open Banking payment where your payment provider supports it, with VAT invoices issued automatically and refunds recorded against the order.

    Payment and paperwork arrive together.

  • Staff review queue

    A workspace for your London team that sorts applications by stage: awaiting documents, identity pending, due diligence review, ready to file, filed, incorporated. Workload and turnaround reporting show where cases get stuck.

    Nobody has to ask which case is waiting on whom.

  • Renewals and post formation reminders

    Address services, company secretarial packages and the confirmation statement each have their own date. The app keeps one calendar per client company, sends reminders ahead of each deadline, takes renewal payments and alerts your team when a client goes quiet, so an address service is never left running for a company nobody has checked in a year.

    Recurring revenue renews on time and lapsed clients are flagged early.

Who this is for

Four kinds of London firm we usually hear from.

The city has every type of formation business, from online agents selling packages across the country to small practices in the City of London that form a handful of companies a month for existing clients. The right app depends on where your volume comes from, how many of your founders live abroad and how much of the compliance sits with you rather than with a partner firm. These are the patterns we see most often, and each one leads to a different first release.

01

Online formation agents with an international client base

You sell packages to founders across the world who want a London presence. Volume is high, questions repeat and identity checks are now part of every sale. The app has to handle many applications at once, chase missing documents automatically and give your compliance team a queue they can clear quickly, while keeping each client's data separated and access controlled. We also design the upsell points carefully, so a founder adds a service address or mail handling because it helps them, not because a checkbox was pre-ticked.

Automation pays back fastest at high volume.

02

Accountancy practices that form companies for new clients

For a practice, incorporation is the first step of a longer relationship covering bookkeeping, payroll, VAT and annual accounts. Business registration app development London practices ask us about usually means one onboarding flow that collects formation details and engagement letter acceptance together, then hands the client into your existing practice software. Partners get a view of new client sign ups by source, and juniors stop retyping the same director details into three different systems. When a client later needs a second company, the details already held are reused rather than collected again.

03

Law firms advising on corporate structures

Solicitors forming holding companies, joint venture vehicles or subsidiaries for City and Canary Wharf clients need precise share capital records, board minutes and authority trails. Company incorporation app development London law firms commission is less about speed and more about control: who instructed, who approved, which documents were signed and in what order. We also build matter linking, so each new company sits under the client and transaction it belongs to. Fee earners see status at a glance instead of asking the company secretarial team.

04

Company secretarial providers managing existing companies

After formation comes the confirmation statement, officer changes, PSC updates and identity verification for directors who were appointed before the new rules and still need to verify. An app that holds that calendar for each client company, and asks the right person for the right thing at the right time, turns a busy spreadsheet into a service clients can see. Directors confirm details from their phone, upload a new address when they move, and receive a clear record of what was filed for them and when.

Post formation work is where long client relationships are kept.

How a London formation app goes from brief to app stores.

  1. 01Discovery by video callWe map your products, your client sources, the checks your AML supervisor expects and the systems you already pay for. Sessions run by video call with your compliance lead and operations staff in the room.
  2. 02Compliance flow designIdentity, due diligence and approval steps are drawn as a flow your nominated officer signs off before any screen is designed, so the product reflects your written procedures.
  3. 03Client and staff interface designPlain British English screens for founders, many of them abroad, and dense, fast review screens for staff who handle dozens of cases a day.
  4. 04Build and integrationsMobile apps, admin system and connections to Companies House data, your screening provider, payments and practice software, built in short cycles you review.
  5. 05Testing with real scenariosWe test overseas directors, corporate shareholders, rejected names, failed checks and refunds, then submit to the App Store and Google Play under your accounts.
  6. 06Running and improvingAfter launch we watch where applications stall and where staff override the system, and plan the next release from that evidence.

What London formation firms ask before they commit.

A client app, a staff workspace and the links to the services you already rely on.

Most London projects include founder onboarding, identity and due diligence steps, incorporation data capture, payments and a review queue for staff. Firms that sell address services add mail handling and renewals, and company secretarial providers add a calendar of filings for each client company. We agree the first release with you after discovery, based on which products bring in most of your revenue and which manual steps cost your team the most hours each week. Everything else is listed on a roadmap with a reason for waiting.
