Cross-border ecommerce
We check the target platform, your existing entity, key personnel, address, tax, bank collection and product documents first. Fill whatever is missing; when a new entity is truly needed, we then connect company registration, tax IDs, banking, trademarks and ongoing accounting.
Platforms, banks and payment providers review applications independently. We handle planning, documents and filing support, and do not guarantee approval.
Service basics
Company, tax ID, bank, platform and ongoing accounting keep using the same set of entity documents. How you prepare at the start affects onboarding, re-review and maintenance later.
Start from where you are
No duplicate registration if you already have a company, no duplicate tax ID. We look at your current status and target platform together, then decide what to add.
Target country, marketplace, product category, existing stores, key personnel, warehousing and collection methods.
Keep the existing entity when it fits; otherwise compare US, Hong Kong and Singapore options and connect EIN or ITIN as needed.
Check account holder, company name, address, business description, products, fulfilment and personnel for consistency.
Annual returns, bookkeeping and tax, sales tax or VAT, plus platform and bank re-review documents.
Platform coverage
We do not send one generic document pack to every platform. For each marketplace we check entity, personnel, tax, collection, product and fulfilment requirements.
View the platform guideSeller identity or company documents, personnel, tax interview, collection account, address, brand and target marketplace.
Entity usability review, company and tax document alignment, consistency checks; trademarks and accounting when needed.
Company information, tax documents, ecommerce track record, product details, payment setup, plus US fulfilment and returns capability.
We separate entity eligibility from business eligibility, so you are not left with a company but no operating record, products or fulfilment proof.
Enterprise verification for the current market, key personnel or beneficial owner, address, tax, bank, product and warehouse documents.
We assess personnel and entity conditions first, then decide whether a new company, tax ID, address or collection setup is required.
Individual or business seller profile, company name, personnel, collection account and identity verification required by the platform.
Company documents and bank collection documents are checked together to reduce mismatches in name, address or account holder.
Store entity, payment region, company documents, bank account, tax information and the actual business address.
If payment and collection matter most, we prepare entity, bank and business proof around payment-provider KYC instead of only building a store.
Target country, seller identity, store entity, bank collection, tax and product compliance requirements.
We start from the official application entry and your current conditions, then list the documents to add and the services we can handle.
Existing entity review
Send your existing documents and the step you are stuck on. We check whether company status, personnel, address, tax and bank documents can still be used before adding anything.
Entity options
Do not keep an extra company just for the word “local store”. Look at target market, personnel identity, payments, warehousing, tax and maintenance cost first.
Formation support across all 50 states; LLC or C-Corp by business needs, plus registered agent, EIN, internal documents, annual reports and tax filing.
See US company plansCommon reference timeline is 3 to 8 working days; company secretary, HK registered address, bank account, annual return, audit and tax filing can be connected.
See Hong Kong plansWith complete documents and no extra review, common reference timeline is 1 to 3 working days; foreign individuals or companies may hold shares with a qualifying local director.
See Singapore plansDocument pre-review
The point is not whether a file exists, but whether company, personnel, address, tax, bank, store, product and fulfilment information explain each other.
Name, registration number, jurisdiction, status and formation documents.
Names, IDs, shareholding, key personnel and ultimate control.
Registered agent address, main operating address and proof of address explained separately.
Company tax ID, personal tax ID and filing status matched to the actual case.
Account holder, company name, address and bank letters stay consistent.
Brand name, contact details, business description and company entity tell the same story.
Categories, brand rights, authorisations, codes and required product documents.
Warehouse, return address, logistics route and operating records prepared to platform standards.

Tell us the target platform, market, products and existing documents. We first set out what is missing, what comes first and which steps are reviewed by the platform or bank.
Keep using existing companies, tax IDs and collection accounts; no duplicates.
Entity, tax ID, address, bank, trademark and platform documents connected in order.
Which files go to the platform, which to the bank, and which stay for annual review and tax — stated upfront.
Target platform, market, products, existing company, tax ID, collection account, brand and current blockers.
Check whether personnel, address, tax, collection and product information are consistent and usable for the target platform.
Required new items, sequence, expected timeline, third-party fees and follow-up maintenance, all in one document.
Company, tax ID, address, bank or trademark work done within the confirmed scope — no unrelated add-ons.
Company, personnel, address, collection and brand information unified; we keep following up if the platform asks for more.
After onboarding, connect annual returns, bookkeeping, sales tax, VAT and document updates to the actual business.
Verifiable credentials
Company formation, banking, tax, ITIN, marketplace onboarding and IP.
Sales tax, VAT and annual filing scenarios for cross-border sellers.
Registered address and company secretary coverage in three jurisdictions.
Accounts remain subject to bank review; we match business and KYC documents first.
Practical guides
Platform choice, sales tax, address usage and brand ownership are usually handled together with onboarding documents.
Look at target market, products, traffic sources, fulfilment and platform review conditions before picking the main marketplace.
Read the platform guide
Inventory, sales regions, platform withholding and standalone store orders decide where you register and file.
Read the sales tax guide
State filings, bank onboarding and platform verification treat addresses differently — separate them before submitting.
Read the address notes
Brand rights holder, applicant, evidence of use and store entity should be aligned early.

Not sure whether your documents are enough? Send what you have first. We will tell you whether it can still be used and what is missing.
Not necessarily. Check whether company status, personnel, address, tax and bank collection documents meet the platform's current requirements. Reuse what works and add only what is missing.
No. Company registration is only part of the document chain; platforms may also review personnel, beneficial owners, address, tax, bank, products, brand, fulfilment and operating history. We provide pre-review and filing support; the platform makes the final decision.
Yes. With an existing company, tax ID and collection account, we can start with a consistency check and then decide whether a new entity, tax ID, address or banking service is needed.
Not automatically. Registered agent address, company registered address, mailing address and actual business address serve different purposes; provide verifiable documents that match what each institution currently asks for.
It depends on the platform and category. Some platforms allow entity and basic documents first, with brand registry later; if your category, brand programme or channel requires a trademark, plan it early.
It depends on the platform and provider. Account holder, company name, controlling person and supporting documents are usually checked; unclear entity relationships make review and remediation harder.
Look at the rejection reason, previous submissions and account status. Appeal with the requested documents, correct wrong information, and avoid repeated resubmission when a key requirement is simply not met.
Depending on jurisdiction and business: annual reports, annual returns, bookkeeping, corporate tax, sales tax or VAT, address and company document updates, and periodic bank or platform KYC.
