TDS 194J business and personal both service combined bill

No, you only need to consider the amount you will be claiming as a business expense to determine TDS. 

Many accountants (especially CAs) will say if it's in one bill then the whole value is subject to TDS, but there is no such rule.

Generally, TDS is applied on expenses and not on payments.

Even if the business expense component was over 30,000, you only need to deduct on the business component, not on personal / reimbursement etc. Just keep the distinction clear, and remember in the return to mention only the business expense figure as the base.
