SQL Query joining 5 tables - sql

Question

Trying to create a query to select all jobs that are unpaid and who the customer is for that job.
So the is required to first work out a calculation of what they owe (by a sum of s_partorders qty x price found in s_parts) and then minus what they have paid from s_payments.
This query joins it all together but I don't know how to group it by jobNumber because there can be multiple payments and multiple part orders.
SELECT a.jobNumber, a.customerID, a.quoteStatus, a.costDelivery, a.costCallout, a.costLabour, b.customerID, b.firstName, b.lastName, c.paymentID, c.jobNumber, c.amount, d.orderID, d.jobNumber, d.partID, d.quantity, e.partID, e.sellPrice
FROM s_jobcards a
INNER JOIN s_customers b ON a.customerID = b.customerID
INNER JOIN s_payments c ON a.jobNumber = c.jobNumber
INNER JOIN s_partOrders d ON a.jobNumber = d.jobNumber
INNER JOIN s_parts e ON d.partID = e.partID
WHERE a.quoteStatus = 0
Sorry it's quite messy and incomplete...
Included table structure and some test data.

Use outer joins where there might be no matching records, and aggregating data to jobnumber before joining will assist in ensuring the numbers are accurate:
select
j.jobNumber, j.customerID, j.quoteStatus, j.costDelivery, j.costCallout, j.costLabour
, c.customerID, c.firstName, c.lastName
, p.parts_sellprice
, sum(jp.amount) as paid
from s_jobcards as j
inner join s_customers as c on j.customerID = c.customerID
left outer join s_payments as jp on j.jobNumber = jp.jobNumber
left outer join (
select
d.jobNumber, sum(d.quantity * e.sellPrice) parts_sellprice
from s_partOrders d
left outer join s_parts e ON d.partID = e.partID
group by
d.jobNumber
) as p on j.jobNumber = p.jobNumber
group by
j.jobNumber, j.customerID, j.quoteStatus, j.costDelivery, j.costCallout, j.costLabour
, c.customerID, c.firstName, c.lastName
;
nb: I have assumed the sell price is multiplied by quantity
see this sqlfiddle demo: http://sqlfiddle.com/#!2/96f4c/1

j.jobNumber, j.customerID, j.quoteStatus, j.costDelivery, j.costCallout, j.costLabour

from s_jobcards as j
inner join s_customers as c on j.customerID = c.customerID
left outer join s_payments as jp on j.jobNumber = jp.jobNumber
left outer join (
