Failed to retrieve company

Error message

Failed to retrieve company

What it means

After confirming a CompanyCode is set, ExportTaxCodesAsync looks it up among the companies returned by GetAccountCompaniesAsync. If no company's companyCode matches the stored value, it throws 'Failed to retrieve company'. The stored code is stale relative to what Avalara reports.

Solutions

Re-fetch companies ('Get account companies') and reselect the correct company.
Verify the company still exists in the Avalara admin.
Ensure the credentials point at the expected account (sandbox vs production).
Save settings and retry the export.

Example fix

// before
var selectedCompany = (await GetAccountCompaniesAsync())
    ?.FirstOrDefault(company => _avalaraTaxSettings.CompanyCode.Equals(company?.companyCode))
    ?? throw new NopException("Failed to retrieve company");

// after - list available codes to aid recovery
var companies = await GetAccountCompaniesAsync();
var selectedCompany = companies?.FirstOrDefault(c => _avalaraTaxSettings.CompanyCode.Equals(c?.companyCode))
    ?? throw new NopException($"Failed to retrieve company '{_avalaraTaxSettings.CompanyCode}'. Available codes: {string.Join(", ", companies?.Select(c => c.companyCode) ?? Array.Empty<string>())}");

Defensive patterns

Strategy: validation

Validate before calling

// Verify the stored code still exists before exporting
var companies = await taxManager.GetAccountCompaniesAsync();
var exists = companies?.Any(c => _avalaraTaxSettings.CompanyCode.Equals(c?.companyCode)) ?? false;
if (!exists)
    throw new NopException($"Stored company '{_avalaraTaxSettings.CompanyCode}' no longer exists.");
await taxManager.ExportTaxCodesAsync();

Prevention

Re-fetch companies after any account/credential change.
Revalidate the selected company before each export.
Prompt reselection when the stored code is missing from the live list.

When it happens

Trigger: GetAccountCompaniesAsync returned companies, but none has a companyCode equal to _avalaraTaxSettings.CompanyCode - the company was deleted, renamed, or the credentials now point at a different account.

Common situations: Company deleted or its code changed in Avalara; account switched; stale cached settings; company was selected against a different (sandbox vs production) account.
